Every dealer term,
finally explained.

A fee charged at the start of a lease, typically $500-$1,000.

The acquisition fee (sometimes "bank fee") is a one-time charge at lease origination by the leasing company to cover administrative costs of setting up the lease. It's usually $500-$1,000 and is rarely negotiable, but you can sometimes roll it into the cap cost rather than pay it upfront. Be aware: dealers sometimes mark up the acquisition fee on top of what the lease company charges, which IS negotiable.

[GAP](/glossary/gap-insurance), tire-and-wheel, key replacement, paint protection, anti-theft. Almost always F&I upsells at 2-4x aftermarket pricing.

Add-on insurance products are the menu of optional protection plans sold in the F&I office after the vehicle price is set: GAP insurance, tire-and-wheel coverage, key replacement, paintless dent repair, paint protection, windshield protection, and anti-theft. Each plan costs the dealer $50-$300 wholesale and sells at $500-$1,200 retail — 2x to 6x markup. Identical or better coverage exists aftermarket: your auto insurer's GAP rider runs $20-$60/year vs. $700 at the dealer; tire-and-wheel from Discount Tire is half the dealer price. Default to "no" on every add-on in F&I; if you decide later you want one, you can buy it aftermarket within the factory-warranty window.

Cap cost = the negotiated vehicle price (pre-incentives). Adjusted cap cost = cap cost minus [cap cost reduction](/glossary/cap-cost-reduction) and applicable rebates.

On a lease, the gross cap cost is the agreed-upon vehicle price before any rebates or down payment — equivalent to the negotiated selling price on a financed deal. The adjusted cap cost is the gross cap cost minus any cap cost reduction (down payment), minus applied manufacturer incentives (lease cash, conquest cash, loyalty), minus any trade-in equity. The adjusted cap cost is the actual financed amount used in the monthly payment calculation: (adjusted cap cost minus residual value) divided by the lease term, plus interest charges on the average of cap cost and residual at the money factor. Always negotiate the gross cap cost FIRST as if you were buying, then layer rebates and cap reduction on top. Negotiating directly on adjusted cap cost lets the dealer hide markup in the gross figure.

A line-item markup over MSRP. Almost always pure dealer profit. Refuse it.

ADM is a "market adjustment" line item dealers add when they believe demand allows them to sell above MSRP. During the 2021-2023 supply shortage these were $5,000-$20,000+ on hot vehicles. In 2026 with inventory recovering, ADMs should generally be refused. If the dealer won't drop it, drive 100 miles — there's another dealer who will sell at MSRP.

Parts or accessories not made by the original manufacturer.

Aftermarket parts are made by third-party manufacturers, not the OEM (original equipment manufacturer). Aftermarket warranties, paint protection, GAP insurance, and accessories are usually significantly cheaper than dealer-sold versions of the same product. The dealer's "paint protection" for $699 vs. an aftermarket ceramic coating for $200 from a detail shop — same end result, different price.

The true yearly cost of a car loan including interest and fees. Lower APR = cheaper loan.

APR is the annualized interest rate plus required loan fees, expressed as a percentage. It's the single most important number to compare when shopping auto loans — a 1% APR difference on a $30,000 / 60-month loan is roughly $1,000 in total interest. APR depends on credit score (excellent 720+ gets best rates, subprime <620 gets penalty rates), loan term (longer terms usually have higher APR), and lender (credit unions almost always beat dealer financing). Always pre-qualify with multiple lenders before shopping.

A used-car sale with no warranty. Buyer assumes all repair risk.

An as-is sale is a vehicle sold "with all faults" — the seller makes no representations about condition and provides no warranty. Most state lemon laws don't apply to as-is sales. Always get a pre-purchase inspection before agreeing to as-is. Federal Trade Commission requires dealers to display a Buyer's Guide on used vehicles indicating as-is or warranty status.

Products sold in the F&I office after the price is agreed: warranty, GAP, etc.

Back-end products are the add-ons sold in the Finance & Insurance office after you've negotiated the vehicle price. These include extended warranty (vehicle service contract), GAP insurance, tire & wheel coverage, key replacement, paint protection, and anti-theft. The F&I manager's job is to sell these — they earn commission on each one. Most are sold at 100%+ markup over wholesale and can be bought aftermarket cheaper.

Comprehensive new-car warranty covering most parts, except wear items.

The bumper-to-bumper warranty (also called "basic warranty") covers virtually every part of a new vehicle except routine wear items like brake pads, wiper blades, and tires. Typical duration: 3 years/36,000 miles, though some manufacturers (Hyundai, Kia, Genesis) extend to 5/60,000. Bumper-to-bumper is included in the new-car price — never pay extra for it.

The actual interest rate the lender offers the dealer. The dealer marks it up.

The buy rate is the rate the lender will give the dealer for your loan. The dealer can mark it up before quoting it to you (called "rate bumping") and keeps the spread as profit (finance reserve). If you walk in with outside financing pre-approved at 6%, the dealer's buy rate may actually be 5.5% — meaning they could match or beat your rate while still profiting. Always ask the dealer to "match my pre-approval rate" rather than accept their first offer.

The "price" of a leased vehicle. What you negotiate down at lease signing.

In a lease, the cap cost is the equivalent of the purchase price — it's the agreed-upon value of the vehicle that the lease payment is based on. A lower cap cost = lower monthly payment. Always negotiate cap cost FIRST as if you were buying, then convert to a lease. Dealers will sometimes try to skip cap cost negotiation and jump straight to monthly payment — that's a manipulation tactic.

The lowest [cap cost](/glossary/cap-cost) the dealer will accept on a lease before walking — internal floor, never quoted.

The cap cost floor is the lowest cap cost a dealer is willing to sign on a lease deal before they're losing money against invoice, holdback, and dealer cash. Dealers never voluntarily disclose this floor — they negotiate from MSRP downward. Estimate it by working invoice minus holdback (typically 2%) minus dealer cash (varies by program) minus any manufacturer-to-dealer trunk money. On a $50,000 MSRP vehicle, the realistic cap cost floor is often $46,000-$47,500, meaning the dealer has $2,500-$4,000 of room. Knowing this number gives you a credible counter-offer floor in negotiation.

A down payment on a lease. Reduces monthly payment but is non-refundable.

Cap cost reduction is the lease equivalent of a down payment. It reduces the cap cost (and therefore the monthly payment) but you do NOT get it back at lease end — and if the car is totaled early, the down payment is lost. Most lease experts recommend zero or minimal cap cost reduction; pay only the first month, taxes, and acquisition fee.

The manufacturer's in-house finance arm (Kia Motors Finance, GMF, Ford Credit, Toyota Financial). Sets the rates dealers use on that brand's leases and loans.

A captive lender is the financing subsidiary owned by a vehicle manufacturer — Toyota Financial Services, Ford Motor Credit, GM Financial, BMW Financial Services, Honda Financial Services, Kia Motors Finance, and so on. Captives publish a monthly rate sheet (buy rates and money factors tiered by credit) that dealers use on every lease and most loans for that brand. Captives subsidize promotional rates (subvented rates) and lease cash to move slow inventory. Knowing the captive's public buy rate before the F&I office means the dealer can't rate-bump you without you catching it. Edmunds and LeaseHackr publish current captive rate sheets by region.

A vehicle history report showing accidents, ownership, service records.

Carfax (and competitors AutoCheck, ClearVin, VinAudit) sell Vehicle History Reports based on data aggregated from DMV, insurance, repair shops, and auctions. A Carfax report shows reported accidents, title issues (salvage, flood, lemon), ownership history, mileage trail, and some service records. Carfax is NOT comprehensive — minor accidents repaired without insurance claims often don't appear. Always pair a VHR with a pre-purchase inspection by an independent mechanic.

[Positive equity](/glossary/positive-equity) from a paid-down trade applied as the down payment on the next vehicle.

Carry-over equity is the dollar value left over after your current loan pay-off is settled from the trade-in value — the surplus carries forward to the next deal as a down payment or cap cost reduction. Example: trade worth $24,000, loan pay-off $18,000 = $6,000 carry-over equity that the dealer applies as your down payment on the new car, no cash out of pocket required. Carry-over equity is the cleanest way to fund a new purchase and the financial mirror image of negative equity. Always verify the dealer's carry-over math against your written pay-off letter and a written Carmax/Carvana offer — dealers occasionally understate trade value or overstate pay-off to capture the gap.

Paying cash forfeits the dealer's [finance reserve](/glossary/finance-reserve) commission. Dealers often quote cash buyers worse than financed buyers as a result.

Counterintuitive but true: dealers usually prefer financed buyers over cash buyers because financing earns them dealer reserve — a $500-$2,000 commission on the loan they would lose on a cash deal. Many dealers won't disclose their best price until they think you're financing through them. The pro move: negotiate as a financed buyer, lock the OTD in writing, then announce you're paying cash at the F&I office (or finance one month and pay off immediately if your loan has no prepayment penalty — check the contract first). This captures the financed-buyer pricing without giving up the reserve to the dealer over the life of the loan.

A co-signer guarantees the loan but is not on the title. A co-borrower is jointly on the loan AND the title. Both take credit damage if you default.

A co-signer and a co-borrower both create joint liability for an auto loan, but the legal structures differ. A co-signer guarantees repayment if the primary borrower defaults but is NOT on the vehicle title — they take the credit hit without ownership rights. A co-borrower is jointly named on both the loan AND the title, with equal ownership and equal responsibility. Lenders sometimes require co-borrowers (not co-signers) on subprime applications to share underwriting risk. For relationships that may end (married couples, romantic partners), co-borrower is cleaner because both parties have title rights to sell or refinance. For pure credit support (parent helping a young adult build credit), co-signer keeps title in the primary borrower's name. Both structures damage the co-party's credit immediately if the primary borrower misses payments — sign cautiously.

A manufacturer rebate for switching from a competing brand (or staying loyal).

Conquest cash is a manufacturer incentive ($500-$2,000) for "conquering" a customer from a competing brand — often paid when a Toyota owner buys a Honda, for example. Loyalty cash is the opposite — paid for staying with the same brand. These rebates are publicly listed on the manufacturer's website and should be applied to your deal. Dealers sometimes "forget" to mention them; check before signing.

A second person who is also legally liable for the loan.

A cosigner agrees to be equally liable for the auto loan if the primary borrower defaults. Cosigners are required when the primary borrower has insufficient credit, low income, or no credit history. The cosigner's credit is at risk if the primary borrower misses payments. Cosigning is legally a serious commitment — the cosigner is on the title and can be sued for the full loan balance.

Used vehicles inspected and warrantied by the manufacturer. Premium of $1,500-$3,500 over non-CPO; often worth it on luxury brands.

A Certified Pre-Owned (CPO) vehicle is a used car that passed a manufacturer-defined multi-point inspection (typically 150-200 points) and comes with an extended factory-backed warranty — usually 1-2 additional years of bumper-to-bumper plus 7 years/100,000 miles powertrain from original in-service date. CPO premium: $1,500-$3,500 over equivalent non-CPO. Worth it on: German luxury (BMW, Audi, Mercedes — out-of-warranty repairs are brutal), high-mileage trucks, and any vehicle with a complex hybrid or EV powertrain. Skip it on: Toyota/Honda economy cars with under 60k miles (the regular warranty is enough), or any CPO from a non-franchise dealer (third-party "certifications" are marketing, not real warranty coverage). Always verify the certifying dealer is the brand's franchise — Toyota CPO only counts at a Toyota dealer.

How long a specific vehicle has been sitting unsold. Past 60 days = the dealer is bleeding [floor plan](/glossary/floor-plan) interest and motivated to discount.

Days on lot (or "days in inventory" / "days supply" / "aged unit") is how long a specific VIN has been sitting on the dealer's lot unsold. The longer the count, the more floor plan interest the dealer has paid carrying the car — typically $5-$15/day on a $40,000 vehicle. At 90 days, the dealer has burned $450-$1,350 of margin just holding the unit, and most manufacturers begin pulling rebate support after 100-120 days. Dealers desperately want aged units off the lot. Find days-on-lot on CarGurus, Autotempest, or by checking the dealer's website history via the Wayback Machine. Any unit past 60 days is a strong target; past 90 days is a fire sale waiting to happen.

A pre-installed bundle (nitrogen, paint/fabric protection, etching) written into the price before you arrive — sold as non-removable. It is removable. Refuse it by name.

A dealer add-on package is a bundle of low-cost accessories the dealer installs (or claims to) and writes into the quote as one line item — often branded "Protection Package," "Appearance Package," "Advantage Package," or store-specific names like "Love Package." Real examples Motrix has pulled from live dealer quotes: a $1,495 "Love Package" on a 2016 Subaru WRX and a $1,495 "Appearance Package" on a 2026 WRX lease. The bundle usually combines nitrogen fill, paint/fabric protection, and VIN etching — items that together cost the dealer well under $150. Dealers present it as mandatory or "already installed," but it is almost always removable: if it is not on the factory invoice, refuse it by name and have it struck from the price. Treat it like any other junk fee and get a revised out-the-door price.

Manufacturer-to-dealer incentive. Hidden from buyers but reduces the dealer's real cost.

Dealer cash is money the manufacturer pays the dealer — separate from any consumer rebate. The dealer doesn't have to pass it on. It effectively lowers the dealer's cost on a vehicle without changing the invoice price. Dealer cash on slow-moving models can be $1,000-$5,000+. Sites like CarsDirect or Edmunds occasionally publish current dealer cash programs by region.

A bogus fee for prep the manufacturer already pays for. Refuse it.

Pre-Delivery Inspection (PDI) is part of the dealer's standard process — they receive the car from the manufacturer, inspect it, prep it, and deliver to you. The manufacturer pays the dealer for PDI as part of their dealer compensation. When dealers add a "PDI" or "dealer prep" fee on top, they're double-dipping. Always refuse this fee.

The dealer's commission on financing. Same concept as [finance reserve](/glossary/finance-reserve) — eliminated by [pre-approval](/glossary/pre-approval).

Dealer reserve (also called "finance participation" or "rate participation") is the commission the dealer earns when arranging your loan through a captive or third-party lender. The lender quotes a buy rate; the dealer quotes you a "contract rate" 1-3 percentage points higher and pockets the spread as reserve. Most lenders cap reserve at 1-2.5 points or $1,500-$2,000 absolute. On a 60-month $35,000 loan, a 2-point rate bump costs you roughly $2,000 in total interest. Walk in with a credit union pre-approval and the dealer has to match or beat your rate to capture any reserve — the spread you save is real money.

When dealer A swaps a vehicle with dealer B to fulfill your specific spec. Often takes 3-7 days.

A dealer trade is when one dealer trades inventory with another dealer to get the exact vehicle (year/trim/color/options) a customer wants. Common when a dealer doesn't have your spec in stock but a partner dealer does. Pros: you get the exact car you want. Cons: can take 3-7 days, the transferring dealer may not be incentivized as hard on price, and some dealers add a small "dealer trade fee" (refuse this — it's their cost of doing business). If a dealer trade is required, lock the OTD price in writing BEFORE the trade is initiated so the price doesn't shift on arrival.

How much value a car loses over time. Heaviest in the first 3 years.

Depreciation is the loss of value as a vehicle ages. New cars lose 20-30% in year one, then ~15% per year through year five. Some makes hold value better (Toyota, Subaru, Porsche) and some are notorious for fast depreciation (luxury sedans, electrics with rapid tech turnover). Understanding the depreciation curve is key to deciding whether to buy new, buy used, or lease.

A non-negotiable manufacturer fee for shipping the car from factory to dealer. Set by manufacturer.

The destination charge (or "freight" or "delivery fee") is what the manufacturer charges to ship the vehicle from the factory or port to the dealer. It's set by the manufacturer, listed on the Monroney sticker, and IS legitimate — same charge whether you buy the car in Florida or Alaska. Typical destination charges: $1,200-$1,800. Trucks and full-size SUVs are usually $1,500+. The destination charge is non-negotiable but you should verify the dealer is charging the manufacturer's exact rate and not adding to it.

Charged at lease-end ($300-$500) just for turning the car in.

The disposition fee is charged by the leasing company at the end of a lease when you return the car (not when you buy it out). It covers their cost of taking the car back, inspecting it, and selling it at auction. Disposition fees are usually $300-$500 and are non-negotiable on most leases. The fee is waived if you lease another car from the same manufacturer.

A flat fee for processing paperwork. State-capped in some states; uncapped elsewhere.

The documentation fee is what the dealer charges for handling registration paperwork. Actual cost: $40-$80. Typical charge: $300-$995, though uncapped states run higher — Motrix has pulled a real Georgia quote charging $1,449 for the same paperwork a California dealer charges the $85 cap for (a 17x spread). Some states cap doc fees (CA $85, NY $175, TX $225) but many (FL, AL, GA) don't. If your state caps doc fees, never pay above the cap. If your state doesn't cap them, negotiate the doc fee down or get an equivalent reduction in the vehicle price to offset.

Government fuel-economy estimate (city/highway/combined MPG).

The Environmental Protection Agency tests every new vehicle and publishes city, highway, and combined MPG ratings. EPA estimates are based on standardized test cycles — real-world MPG varies by 10-20% depending on driving style, terrain, and climate. Compare EPA ratings on fueleconomy.gov, the official government database.

Lease-end fees for damage beyond "normal" wear. Typical bill: $500-$3,500 depending on inspector findings. See [wear and tear](/glossary/wear-and-tear).

Excess wear and tear charges are the lease-end bill for vehicle damage that exceeds the contract's "normal wear" definition. Common findings: dents over a credit-card size, scratches through the clearcoat, cracked windshields, curb-rashed wheels, interior stains, smoke odor, missing keys or floor mats, tire wear below the contract minimum (typically 4/32" tread). Inspector reports run $500-$3,500 in total charges, sometimes higher on luxury vehicles. Defenses: buy a wear-and-tear protection rider at lease signing for $400-$800 (cheaper than likely repair bills for families with kids or pets), repair obvious damage yourself before turn-in (a $300 windshield replacement is cheaper than a $700 lessor charge), and request an independent pre-turn-in inspection to dispute disputed items. See full breakdown at wear and tear.

Coverage for repairs after factory warranty ends. Often overpriced at the dealer.

An extended warranty (technically a Vehicle Service Contract — true warranties only come from manufacturers) covers repairs after the factory bumper-to-bumper warranty expires. Dealer-sold VSCs are often $1,500-$4,500 with 50%+ markup. Third-party providers (Endurance, CarShield, Autopom!) often sell equivalent coverage for half the price. ALWAYS decline the dealer VSC and shop independently if you want one.

The room where the F&I manager sells you back-end products after price is set.

After you negotiate the vehicle price with the salesperson, you get handed off to the F&I manager. Their job is to sell back-end products: extended warranty, GAP, tire & wheel coverage, paint protection, anti-theft. Each upsell adds $500-$3,000 to the deal. F&I managers are heavily commissioned and trained in objection handling. Default to "no" on everything unless you've specifically researched a product in advance.

Order a car directly from the factory with the exact spec you want. Takes 6-12 weeks but typically priced at MSRP.

A factory order (or build-to-order) is when you order a vehicle directly from the manufacturer's production line with your exact specifications — color, trim, options, accessories. Pros: exact spec, often at MSRP without dealer markup since there's no inventory game, and you avoid dealer-installed add-ons. Cons: 6-12 week wait, requires deposit ($500-$1,000 typical), and not all manufacturers offer factory ordering for all models. Tesla, Ford, and Chevrolet have well-established factory order processes; Toyota and Honda are more limited. Ask the dealer about their factory order program — it's a low-pressure way to get exactly what you want.

Profit the dealer makes on your loan. Eliminate by bringing your own financing.

When you finance through the dealer, the dealer earns a commission ("finance reserve") from the lender — typically 1-3% of the loan amount, capped at $1,500-$2,000 by most lenders. The dealer adds this margin to the lender's buy rate before quoting your APR. Walking in pre-approved by your bank, credit union, or Capital One Auto Navigator eliminates this margin entirely.

How dealers finance their inventory. Days-on-lot = pressure to sell.

Dealers don't own most cars on their lot — they finance them through "floor plan" loans from the manufacturer or a bank. Floor plan interest accrues daily on every car. Cars sitting 60-90+ days are bleeding the dealer's margin via floor plan interest. This is why "days on lot" is a powerful negotiation lever — a 100-day-old car has burned $400-$800 in floor plan interest already, and the dealer is desperate to recover.

Insurance the lender buys and adds to your loan if you let your own auto insurance lapse. Costs 3-10x retail coverage.

Force-placed insurance (sometimes "lender-placed" or "collateral protection insurance") is what your auto lender adds to the loan if your own comprehensive and collision coverage lapses below the contract's minimum requirements. The lender is protecting their collateral, not you — force-placed policies cover only the lender's interest, not liability, not your medical bills, not your replacement vehicle. Premiums are typically $1,500-$4,000 per year, financed onto the loan principal, vs. $400-$1,000 for normal auto insurance. Letting your own coverage lapse is one of the most expensive mistakes a financed buyer can make. Most loan contracts give the lender 30 days notice before force-placing. Maintain continuous coverage and verify with the lender after any policy change.

A worksheet that confuses you about price, trade, down payment, and monthly. Refuse it.

The four-square is a piece of paper divided into quadrants — vehicle price, trade-in, down payment, and monthly payment. Salespeople use it to manipulate four numbers simultaneously, making it hard to track which one is actually moving. The defense: insist on negotiating ONE number at a time, starting with out-the-door price. Read more in our four-square deep dive.

Front-end = profit on the vehicle price. Back-end = profit from financing and [F&I products](/glossary/fi-office). Back-end is where most dealer profit lives today.

Dealer profit splits into two buckets. Front-end profit is the margin between the dealer's cost (invoice minus holdback minus dealer cash) and the price you pay for the vehicle — typically $500-$3,000 per unit in 2026, often razor-thin on competitive segments (Toyota Camry, Honda Civic). Back-end profit comes from the F&I office: finance reserve on the loan markup, extended warranty margin, GAP, paint protection, and other add-on products. Average back-end profit per deal in 2026: $1,800-$2,500. This is why F&I managers are the highest-paid people in most dealerships and why declining every back-end product is the single biggest savings lever for buyers. Front-end gets headlines; back-end pays the dealer's mortgage.

Covers the difference between car value and loan balance if totaled. Often overpriced at dealer.

Guaranteed Auto Protection (GAP) insurance covers the gap between what your car is worth and what you owe on the loan if the car is totaled or stolen. Useful for high-finance, low-down-payment buyers in the first 1-2 years when depreciation outpaces principal payoff. Dealer GAP: $500-$900. Your auto insurance company's GAP: usually $20-$60/year. Always buy from your insurer, never the dealer.

An extended [GAP](/glossary/gap-insurance) product that also reimburses your auto-insurance deductible after a total loss.

GAP+ (also "GAP Wrap" or "Deductible Reimbursement GAP") is a premium tier of GAP insurance that pays both the loan-balance gap AND your auto insurance deductible (typically $500-$1,000) after a total loss. Standard GAP covers only the loan gap; the deductible is your out-of-pocket. GAP+ adds $50-$150 to the GAP premium and is sold heavily in the F&I office because the wrap is high margin. Worth it if you carry a $1,000+ deductible AND are buying GAP anyway. Skip the dealer version regardless — your auto insurer or credit union sells equivalent wrap coverage at 30-50 percent of dealer pricing. See GAP insurance: when it is worth the premium.

A full credit check that affects your FICO score by ~5 points and stays on your report for 2 years.

A hard inquiry (or "hard pull") is a full credit check pulled when you formally apply for credit — auto loan, mortgage, credit card. Each hard pull drops your FICO 3-8 points temporarily and stays on your report for 24 months. For auto loans, FICO's "rate shopping window" treats all hard pulls within 14-45 days for the same loan type as a single inquiry — so applying to 4-5 lenders within two weeks counts as one pull on your score. Dealers run hard pulls when finalizing financing; one dealer pull is normal, but if a dealer shops your app to 8 lenders in different windows your score takes multiple hits.

A 1-3% rebate the manufacturer pays the dealer after a sale. Hidden profit.

Holdback is 1-3% of the MSRP that the manufacturer pays the dealer AFTER the sale closes. It's designed to help dealers cover floor plan interest. Holdback is hidden from buyers — when a dealer says "we're selling at invoice, no profit," they're lying because they still get holdback. Holdback on a $30,000 car is typically $300-$900. Some dealers will give up part of holdback as part of negotiation if you push hard.

Total cash due at lease signing: first month + [acquisition fee](/glossary/acquisition-fee) + taxes + fees + any [cap cost reduction](/glossary/cap-cost-reduction).

The idle payment (also "drive-off" or "inception") is the total dollar amount you write a check for at lease signing — distinct from the monthly payment. It includes: first month's payment, acquisition fee ($500-$1,000), upfront sales tax (varies by state), registration and title fees, doc fee, plus any cap cost reduction you elect. Lease deals are commonly advertised as "$0 down" which means zero cap cost reduction — but you still owe the inception/idle payment, often $1,500-$3,500. Always get the exact drive-off itemized in writing; this is where dealers slip in VIN etching, nitrogen, and other junk fees hoping you focus only on the monthly number.

Loans made directly by the dealer (not a third-party lender). Usually predatory rates aimed at [subprime](/glossary/subprime) buyers.

In-house financing — also called "Buy Here Pay Here" (BHPH) — is when the dealer is the lender, not a bank or credit union. BHPH dealers target buyers with bad credit who can't qualify for traditional auto loans. APRs are typically 20-30% (sometimes higher), down payments are large, terms are short (2-3 years), and vehicles often have GPS trackers / kill-switches for repossession. The vehicles are usually older, marked up 30-50% above wholesale, and sold "as-is." Avoid BHPH if at all possible — a credit union subprime auto loan is almost always dramatically cheaper, even with a 580 FICO.

Total cash due at lease signing — first month, [acquisition fee](/glossary/acquisition-fee), upfront taxes, DMV fees, and any [cap cost reduction](/glossary/cap-cost-reduction).

Inceptions (also called "drive-off," "out-of-pocket due at signing," or idle payment) is the total dollar amount you write a check for at lease signing — separate from the monthly payment. Components: first month's payment, acquisition fee ($500-$1,000), upfront sales tax on the cap cost reduction and sometimes on the total payments (varies by state), DMV title and registration fees, doc fee, plus any cap cost reduction you elect. A "$0 down" lease ad means zero cap cost reduction — but inceptions still typically run $1,500-$3,500. Always demand the inceptions itemized in writing before signing; this is where dealers slip in VIN etching, nitrogen fill, and other junk fees when the buyer is focused only on the monthly payment.

What the dealer pays the manufacturer. Public information for most makes.

Invoice price is what the manufacturer charges the dealer for a specific vehicle. It's typically 8-15% below MSRP. Invoice prices are published on Edmunds, KBB, TrueCar, and CarsDirect. Knowing invoice gives you a negotiation floor — but remember the dealer also gets holdback (1-3%) and dealer cash, so they have margin even at invoice. A skilled negotiator targets 1-2% UNDER invoice on most cars.

Covers cost of replacing lost or stolen keys and fobs over 3-5 years. Sold at $300-$600; modern smart keys cost $400-$800 to replace.

Key Replacement Insurance covers the cost to replace lost or stolen vehicle keys and key fobs over a 3-5 year window. Coverage is real — modern smart keys with proximity sensors, push-button start, and immobilizer chips cost $400-$800 to replace at the dealer (key cost $150-$300, programming $100-$250, locksmith trip $100). Dealer plan: $300-$600. Most auto insurance comprehensive policies cover key replacement after theft (not loss) with the deductible. Worth it if you lose keys more than once across the plan period; skip it if you have a track record of not losing them. Aftermarket key insurance from Carchex, AAA, and some credit unions runs 40-60 percent of dealer pricing.

A manufacturer rebate that only applies if you lease (not finance or pay cash) the vehicle. Built into the [cap cost](/glossary/cap-cost) reduction.

Lease cash is a manufacturer incentive that exclusively applies to leased deals — typically $500-$3,000 — and is applied as a cap cost reduction rather than paid to you in cash. Lease cash is usually separate from and stackable with conquest cash, loyalty cash, and general rebates. It does NOT transfer to a financed deal — switching from lease to finance forfeits the lease cash. Always check the manufacturer's current lease cash on Edmunds incentives or the brand site; dealers occasionally retain lease cash for themselves rather than passing it on to the cap cost.

A manufacturer offer to end your existing lease 1-6 months early with no penalty if you lease another vehicle from the same brand.

A lease pull-ahead is a manufacturer-sponsored program that waives your final 1-6 lease payments AND the disposition fee if you sign a new lease with the same captive lender. Pull-aheads typically appear when the manufacturer wants returning inventory for the certified pre-owned channel or to clear current-year stock. Real value: 3-6 payments waived ($1,500-$4,000) plus the $350-$500 disposition fee. The catch: you give up the ability to shop competing brands, which can cost more than the pull-ahead saves if a competitor has a better lease program that month. Always run both math scenarios before accepting a pull-ahead offer.

A current-year model still on lot when next-year arrives. Heavy discounts available.

A "leftover" is a current-model-year vehicle still sitting on the dealer's lot when the next model year arrives. Once new-year inventory shows up (usually August-October), dealers MUST clear leftovers — they can't legally sell them as new the following year, and they're burning floor plan interest. Discounts of 10-20% off MSRP on leftovers are common. The trade-off: you accept "older" model year for warranty/resale purposes.

A vehicle with a substantial defect that persists despite repair attempts. State [lemon laws](/glossary/lemon-law) provide remedies.

A "lemon" is a vehicle with a substantial defect that the manufacturer has failed to repair after a reasonable number of attempts (typically 3-4 attempts for the same issue, or 30+ days out of service within the warranty period). State lemon laws define the exact thresholds. If your car qualifies, the manufacturer must refund or replace it. Document EVERYTHING — every repair invoice, every dealer phone call, every loaner-car pickup. File the lemon law request in writing to the manufacturer (not the dealer) with all documentation attached.

State laws requiring manufacturers to refund/replace cars with persistent defects.

Lemon laws vary by state but generally require manufacturers to refund or replace a vehicle if a substantial defect persists after a "reasonable number of repair attempts" (typically 3-4 attempts for the same issue, or 30+ days out of service). Lemon law applies to new vehicles in all states; some states (including California, NY, NJ) extend lemon law to used vehicles within a certain warranty period. File a written request to the manufacturer if you suspect you have a lemon — keep all repair records.

On a financed car, you are the title holder and the lender is the lien holder. On a leased car, the captive lender is BOTH — you are neither.

A lien holder is the entity that has a security interest in the vehicle until a debt is satisfied. A title holder is the entity legally registered as the owner. On a financed purchase, you are the title holder (your name on the title) and the lender is the lien holder (their name listed as lienholder on the title) — once the loan is paid off, the lien is released and you receive a clean title. On a lease, the captive lender is BOTH the lien holder AND the title holder — you are a registered driver/operator, not an owner. This distinction matters for: (1) selling the vehicle (you cannot sell what you do not own — leases require buyout first), (2) insurance claims (totaled lease vehicles pay the captive, not the lessee), and (3) tax deductions (interest on a financed car may be deductible for business use; lease payments are handled differently). Always confirm which structure you are signing before the F&I conversation.

How many months you have to pay off the loan. Longer term = lower payment but more total interest.

The loan term is the length of the auto loan in months. Common terms: 36, 48, 60, 72, 84 months. Longer terms reduce your monthly payment but dramatically increase total interest paid AND increase the period you're underwater on the loan. The auto industry has been pushing 84-month loans hard because they enable lower payments on more expensive cars — but you'll pay 30-50% more in total interest vs. a 60-month loan. Rule of thumb: 60 months max for a new car, 48 months for used.

When a manufacturer repurchases a defective vehicle under [lemon law](/glossary/lemon-law). Title is permanently branded.

A manufacturer buyback occurs when a vehicle is repurchased by the manufacturer because it qualified as a lemon under state law. The vehicle gets a permanent title brand (usually "Lemon Law Buyback" or "Manufacturer Buyback") that follows it forever. Buyback vehicles are sometimes resold by manufacturers at auction; they may end up on dealer lots at substantial discounts. If considering a buyback purchase: typical discount is 30-50% off comparable clean-title pricing, but you accept a vehicle with a documented defect history. Insurance companies may charge more or limit coverage. Resale value stays low forever. Only worth it if the discount is meaningful AND the underlying defect was definitively repaired (verify with manufacturer service records).

Cash incentive from the manufacturer to consumers. Always apply to your deal.

Manufacturer rebates are direct cash incentives ($500-$5,000+) offered by the automaker to move specific models or trims. Rebates are publicly listed on each manufacturer's website and on Edmunds/KBB. They stack with most negotiated discounts. Dealers sometimes "forget" rebates or claim a rebate "isn't available in your state" — verify directly on the manufacturer's incentives page.

The annual mileage cap on a lease — typically 10k, 12k, or 15k miles per year. Going over costs $0.15-$0.30 per mile at lease end.

The mileage allowance is the per-year mileage cap built into your lease contract — most common at 10,000, 12,000, or 15,000 miles. Higher allowance = slightly higher monthly payment because the leasing company prices in faster depreciation. Going over at lease end is expensive: $0.15 per mile is the cheap end (Toyota, Honda), $0.25-$0.30 is luxury brand standard, and the overage gets billed when you turn in the car. If you drive 18,000+ miles a year, lease with a higher allowance from the start — paying $20/month more for an extra 3,000 miles is cheaper than paying $0.25 x 3,000 = $750 per year in overage. Buying additional miles upfront also costs less than paying overage after the fact (typical: $0.10-$0.15/mile prepurchased).

The lease-end math: total miles driven minus contract [mileage allowance](/glossary/mileage-allowance), multiplied by the per-mile overage rate.

Mileage reconciliation is the lease-end calculation of overage miles and the resulting charge. Formula: actual miles driven minus the contract's total mileage allowance (annual allowance times lease term), multiplied by the per-mile overage rate ($0.15 to $0.30 typical, set in the contract). Example: 39,000 actual miles on a 36-month lease with a 10,000/year allowance = 9,000 overage miles x $0.25 = $2,250 bill at turn-in. Strategies to reduce: buy additional miles upfront at $0.10-$0.15/mile (cheaper than overage at turn-in), buy out the lease and sell the car yourself if the buyout is below market (overage does not apply on a lease buyout), or lease-pull-ahead into a new lease where the captive forgives the overage on the returning vehicle. See mileage allowance.

Illegally tampering with the odometer to show fewer miles. Federal felony.

Mileage rollback is the federal-felony practice of tampering with a vehicle's odometer to display fewer miles than actually driven. Each rolled-back mile inflates the car's value by $0.10-$0.30 — a 50,000-mile rollback adds $5,000-$15,000 to a used car's value. Federal law (the Odometer Act) makes rollback a felony with up to 3 years in prison plus civil penalties. Detect rollbacks via Carfax/AutoCheck reports, inspection station records, oil change stickers, and tire/brake wear inconsistent with stated mileage. If you suspect rollback, walk and report to NHTSA at vinrcl.safercar.gov.

The lease math rule that each $1,000 of [cap cost reduction](/glossary/cap-cost-reduction) lowers your monthly payment by ~$30 on a 36-month lease.

On a typical 36-month lease, every $1,000 of cap cost reduction ("money down") lowers your monthly payment by roughly $28-$32 — call it $30 as a rule of thumb. The math: $1,000 spread over 36 months is $27.78, plus the foregone interest on the money factor (~$2). Lease pros use this to spot bad deals: if a dealer advertises "$3,000 down for $399/month" but the same car at $0 down would be $489/month, that's a $90 reduction for $3,000 — only $30/multiplier, which checks out. If $3,000 down only drops the payment $60/month, the dealer is keeping the difference somewhere (usually inflated money factor or cap cost).

The "interest rate" of a lease, expressed as a small decimal. Multiply by 2400 for APR.

In a lease, the money factor replaces the APR. It's a small decimal like 0.00125 (which equals 3% APR — multiply by 2400 to convert). Dealers will sometimes mark up the money factor without telling you, just like they mark up APR on a loan. ALWAYS ask "what's the buy-rate money factor?" and compare to the rate you're being offered. Tools like Edmunds' lease calculator help spot money factor markups.

Multiply the [money factor](/glossary/money-factor) by 2400 to get the APR-equivalent interest rate on a lease.

The money factor on a lease is a small decimal that functions as the lease equivalent of an APR. To convert to APR, multiply by 2400. Example: money factor 0.00125 x 2400 = 3.0 percent APR. Money factor 0.00250 x 2400 = 6.0 percent APR. The 2400 multiplier comes from the math of how money factor is applied in the lease payment formula — it compresses two parts of the calculation (lease term and a constant) into a single decimal. Always ask the F&I manager for the buy-rate money factor from the captive lender's rate sheet, convert to APR, and compare to current auto loan rates. If the converted APR is above your credit-tier prime rate by more than 1 percentage point, the dealer is marking up the money factor and pocketing the spread as dealer reserve. LeaseHackr and Edmunds publish current buy-rate money factors by region.

Manufacturer's Suggested Retail Price. The window-sticker price. Negotiable on most cars.

MSRP (Manufacturer's Suggested Retail Price) is the price the manufacturer suggests dealers charge — it's what appears on the window sticker (the "Monroney sticker"). MSRP is negotiable on most vehicles. Exceptions: limited-edition or genuinely supply-constrained models where the dealer can sell at MSRP without negotiation. Most modern vehicles transact 5-15% below MSRP.

Parts made by the original manufacturer. Often more expensive than aftermarket equivalents.

OEM parts are made by the same supplier that built the part for the original vehicle assembly. Aftermarket parts are made by other manufacturers — often equivalent quality at lower cost. For warranty repairs and lease returns, OEM parts are typically required. For out-of-pocket repairs, aftermarket usually saves 30-60% with comparable quality from reputable brands.

A bundled set of features sold as a unit. Often a better deal than equivalent à la carte options.

An options package is a bundled set of features sold as one line-item add-on — e.g., "Premium Package" might include heated seats, leather, larger wheels, and a sunroof for $2,500 vs. $4,000 if priced individually. Manufacturers use packages to simplify ordering and to push features that don't sell well à la carte. Read the package contents carefully before buying — you may be paying for features you don't want to get the one you do. Sometimes a higher trim level is cheaper than the base trim plus packages.

Extra fees when buying a vehicle in one state and registering in another. Typical: $50-$300 in title transfer fees plus possible sales tax differential.

Buying a vehicle in one state and registering it in another (common when chasing inventory or better pricing across state lines) triggers a set of additional fees. Components: (1) the selling-state may charge a temporary title or "in-transit" tag fee ($25-$75), (2) your home-state DMV charges a title-transfer fee on the out-of-state title ($50-$150), (3) sales tax is computed at your HOME-state rate, not the selling-state rate — most states reciprocate sales tax credits, but some do not, occasionally resulting in tax paid in both states, (4) emissions and safety inspection requirements differ (California, New York, and Massachusetts have stricter standards), so the vehicle may need modifications or smog testing to register, and (5) some dealers charge an "out-of-state delivery fee" of $100-$500 as pure margin — refusable. Always compute total cross-state cost (including travel and registration delays) against local pricing before chasing a deal across state lines. The savings are real on luxury vehicles in low-tax states; on commodity vehicles, the math rarely works.

The all-in price including tax, title, registration, doc fee, and every other fee. The number that matters.

The out-the-door (OTD) price is the actual total you'll pay — vehicle price + sales tax + title + registration + doc fee + every other fee. It's what you'd write a check for if paying cash. ALWAYS negotiate OTD, never just the vehicle price. Dealers love negotiating "vehicle price" because they can hide $2,000-$3,000 in junk fees that appear in the OTD breakdown later. Get OTD in writing before visiting the dealer.

Marketed as ceramic coating; usually a $50 sealant sold for $499-$899. Refuse.

Dealer "paint protection" packages are typically a $50 ceramic spray applied in 12 minutes of labor — sometimes literally just a sticker on the windshield with no actual application. Real ceramic coatings cost $1,000-$2,000 at a detail shop. Fabric protection is essentially Scotchgard ($8/can) sprayed on the seats. Always refuse these in F&I; if you want real protection, get it aftermarket from a detail shop.

A written quote from your current lender of the exact amount needed to satisfy your loan, valid for 10-14 days.

A pay-off letter (or "10-day payoff") is a written quote from your current auto lender stating the exact dollar amount needed to close your loan — principal plus accrued interest through a specific date. Required when you trade in a financed vehicle, refinance, or sell to Carvana/CarMax. Call your lender or pull it from their app; the figure is usually valid 10-14 days. Pay-off is what determines your positive or negative equity — trade value minus pay-off balance. Dealers occasionally inflate the pay-off in trade-in math hoping you won't verify; always have the lender's written quote in hand before signing.

A prepaid plan for minor dent and ding repairs over 3-5 years. Sold at $500-$900; aftermarket equivalent is $150-$250.

Paintless Dent Repair (PDR) is a real and useful technique — technicians push small dents out from the inside of body panels without repainting. Dealer-sold PDR protection plans bundle a set number of repairs over 3-5 years at $500-$900 retail. Wholesale cost: $80-$150. Most door dings cost $75-$125 to fix out of pocket at an aftermarket PDR shop, meaning a buyer would need 4-6 actual claims to break even on the dealer plan. Skip it in F&I; pay per repair as dents happen. The plan only pays off for buyers in dense urban parking environments who actually file claims aggressively.

When the salesperson sketches numbers on paper to "show the manager." A delay tactic.

When a salesperson "pencils" a deal, they're writing numbers on paper to take to "the manager" for approval. This is partly real (the salesperson doesn't have authority on every number) and partly theater (designed to make you wait, get tired, and lower your resistance). Counter-move: bring distractions (laptop, snacks), set a hard departure time, and don't let the wait pressure you into accepting worse terms.

Trade-in value minus loan [pay-off](/glossary/pay-off-letter). Positive equity is cash toward the new car; negative equity rolls into the new loan.

Equity in a trade-in is current market value minus the remaining loan pay-off. Positive equity = trade is worth more than you owe; the difference becomes a down payment on the next car (or cash back). Negative equity (you're underwater) = you owe more than the trade is worth; dealers will roll the gap into the new loan, which compounds the problem and extends your underwater period. Rule: if you have $5,000+ in negative equity, do not roll it — pay it off in cash, sell privately, or keep the car until you're right-side-up. Get a written Carmax/Carvana offer plus a pay-off letter BEFORE the dealer math starts.

Long-term coverage for engine, transmission, drivetrain. Typically 5/60,000 miles, sometimes 10/100,000.

The powertrain warranty covers the engine, transmission, and drivetrain components — the most expensive parts to repair. Standard coverage: 5 years/60,000 miles. Some manufacturers extend further: Hyundai/Kia/Genesis offer 10 years/100,000 miles, Mitsubishi 10/100,000, GM 5/60,000 (was longer historically). The powertrain warranty is included in the new-car price and transfers (sometimes partially) to subsequent owners. It's NOT a substitute for an extended warranty — extended warranties cover a wider range of components.

A loan offer from your bank or credit union BEFORE you visit the dealer. Game-changer.

A pre-approval is a written commitment from a lender (your bank, credit union, or service like Capital One Auto Navigator) for a specific loan amount at a specific rate. Walking into the dealer pre-approved means: (1) you know your real budget, (2) the dealer can't inflate your APR via finance reserve, and (3) you have leverage — the dealer must beat your rate to keep the financing in-house. Always pre-approve before shopping.

Pre-qualification is a soft-pull estimate. Pre-approval is a hard-pull commitment. Get pre-approval.

Pre-qualification (or "soft pull pre-qual") is an estimate based on a soft credit check — it doesn't affect your score, but the offered rate is not guaranteed. Pre-approval (or "hard pull pre-approval") involves a full credit check and provides a binding rate commitment for a specific loan amount. For car shopping, pre-approval is what you want — it gives you real leverage at the dealer. Most lenders will match credit pulls within a 14-30 day shopping window as a single inquiry, so apply to 3-4 lenders in the same week.

A [manufacturer rebate](/glossary/rebate) is taxed in the pre-rebate price in some states (TX, CA, AZ, NV). A dealer discount is taxed in the post-discount price everywhere.

Most states treat manufacturer rebates and dealer discounts differently for sales tax purposes. A dealer discount is a reduction in the negotiated selling price — sales tax applies to the post-discount price in every state. A manufacturer rebate is technically a payment from the manufacturer to the buyer that the buyer then assigns to the dealer; in roughly half the states (including Texas, California, Arizona, Nevada, and Pennsylvania), sales tax applies to the PRE-rebate price, meaning the buyer pays tax on the rebated amount. Example in Texas: $40,000 vehicle, $2,000 manufacturer rebate, 6.25 percent sales tax. Tax is computed on $40,000 ($2,500) not $38,000 ($2,375) — a $125 tax cost on the rebate. States that tax post-rebate (rebate-friendly): Florida, Illinois, Massachusetts, New York, Ohio, and others. Verify your state's rule before signing — the difference can be $100-$400 on the final TT&L.

A leased car's projected value at lease end. Set by the leasing company; affects monthly payment.

Residual value is the leasing company's prediction of what your car will be worth at lease end (e.g., 60% of MSRP after 36 months). Higher residual = lower monthly payment because you're paying for less depreciation. Residual values are set by the leasing company and not really negotiable, but you can shop different leasing companies for the same car — some have higher residuals than others.

A manufacturer-funded bump to [residual value](/glossary/residual-value) on a lease, lowering the monthly payment.

A residual value booster (or "RV booster" / "MSRP boost") is a manufacturer-funded program that artificially raises the residual value above the bank's baseline number, sometimes by 2-5 percentage points. Higher residual = less depreciation financed = lower monthly payment. Boosters are how brands like BMW, Audi, and Cadillac sometimes hit aggressive advertised lease specials on otherwise slow inventory. The catch: an artificially-high residual makes the lease buyout at term-end uneconomical (you'd pay above market for the car), so plan to return the vehicle, not buy it out. Always check both the boosted and the unboosted residual on LeaseHackr forums before signing.

A credit check that does not affect your FICO score. Used for [pre-qualification](/glossary/pre-qualification) and pre-screened offers.

A soft pull is a credit check that does not affect your FICO score and is not visible to other lenders. Soft pulls power pre-qualifications, employer background checks, your own self-reports (Credit Karma, annualcreditreport.com), and pre-screened "you are pre-approved" mail offers. For car shopping, soft-pull pre-quals from Capital One Auto Navigator, AutoFi, or Chase let you check your real rate without burning credit. The trade-off: soft-pull rates are estimates, not guaranteed — the binding rate only comes from the hard inquiry at the dealer.

You drive home, then dealer calls saying "your loan didn't go through." Predatory tactic.

Spot delivery is when the dealer lets you drive the car home before the financing is fully approved. Days or weeks later, the dealer calls saying "your loan didn't go through, we need a higher rate or a bigger down payment." This is sometimes called yo-yo financing and is illegal in some states. Defense: NEVER drive a car home until the loan is fully funded. Wait for the dealer's call confirming "we have the loan." If they pressure you to take it before final approval, walk.

Manufacturer programs that combine — vs. mutually exclusive incentives where you pick one. Stack everything you qualify for.

Manufacturer incentives (rebates, conquest cash, loyalty cash, military, college grad, first responder, lease cash, finance cash) are either "stackable" (combine with others) or "mutually exclusive" (pick one). The terms are listed in fine print on each program's manufacturer page. Common example: a $1,500 manufacturer rebate stacks with a $750 conquest cash AND a $500 military rebate for $2,750 off — but the 0% APR finance offer may be exclusive with the rebate. Dealers sometimes "forget" stackable incentives or claim two are exclusive when they aren't. Look up the current month's incentive bulletin on Edmunds or the manufacturer site and bring it in writing.

The MSRP-plus-options price on the window sticker.

The "sticker" or Monroney sticker is the federally required window display showing MSRP, options, fuel economy, safety ratings, country of origin, and destination charge. It's named after Senator Mike Monroney who wrote the 1958 law requiring it. The sticker price is the upper bound of negotiation on most cars — you should always pay below it.

A loan made to a borrower with a credit score below ~620. Higher interest rates and stricter terms.

Subprime auto loans are made to borrowers with FICO scores below ~620. APRs are typically 10-25% (vs. prime tier at 4-8%). Subprime loans often require a larger down payment, shorter term, or co-signer, and may include GPS tracking devices for repossession. The subprime auto market is heavily regulated post-2008 due to predatory practices (yo-yo financing, spot delivery, forced add-ons). If you're shopping subprime, get pre-approved through a credit union before visiting a dealer — credit unions offer dramatically better subprime rates than dealer-arranged loans.

Captive lender credit tiers below prime — typically FICO under 620. APRs run 4-8 percentage points above [Tier 1](/glossary/tier-1).

Subprime tiers are the lower bands on a captive lender's monthly rate sheet — typically Tier 4, Tier 5, and "deep subprime" for FICO scores below 620. APRs in subprime tiers run 12-25 percent in 2026 vs. 5-7 percent in Tier 1, even on identical loan terms. Subprime tier customers also face larger required down payments, shorter maximum loan terms, mandatory GPS trackers on some BHPH and deep-subprime loans, and restrictions on stackable rebates. The biggest single move for a subprime buyer: get pre-approved at a credit union before stepping into a dealer. Credit union subprime rates are typically 4-8 points lower than dealer-arranged subprime on the same FICO band.

A manufacturer-subsidized below-market [money factor](/glossary/money-factor) or APR, used to move specific models.

A subvented rate is when the manufacturer (not the lender) pays down the buy rate on a lease or loan to incentivize sales — a "subsidy." Common on slow-moving models, last-year leftovers, or factory pushes. Subvented leases often show a money factor like 0.00001 (effectively 0%) or APRs of 0.9-2.9% on financed deals. The trade-off: subvented programs are usually mutually exclusive with stackable rebates — you pick the cheap rate OR the cash incentive, not both. Run both deals to total cost over the full term; subvented is usually better on lower-priced cars, rebate is usually better on luxury.

The top credit tier on a captive lender's rate sheet. Unlocks the lowest [money factor](/glossary/money-factor) and APR.

Captive lenders (GM Financial, Ford Motor Credit, Toyota Financial, BMW Financial, etc.) tier customers by credit score on internal rate sheets — typically Tier 1 / A+1 at the top (usually 740+ FICO), then Tier 2, 3, 4, and so on. Top-tier customers get the advertised national buy rate; subprime tiers can pay 3-8 percentage points more. Always ask the F&I manager which tier you priced in at — if the answer is anything but Tier 1 with a 740+ score, the dealer is rate-bumping you. Captive tier breakpoints are published on rate sheets dealers receive monthly; sites like LeaseHackr post region-specific copies.

A 3-5 year plan covering road-hazard tire damage and curb-rashed wheels. Sold at $800-$1,500; aftermarket equivalent is $300-$500.

Tire and Wheel Protection plans cover replacement of tires damaged by road hazards (nails, potholes, blowouts) and refinishing of curb-rashed alloy wheels. Dealer pricing: $800-$1,500 for 3-5 years. Aftermarket coverage from Discount Tire ($300-$500) or your auto insurer's comprehensive coverage (already included on most policies for tire damage with a deductible) is half the cost. Useful for buyers with low-profile performance tires ($300+ each), large-diameter aftermarket wheels, or daily commutes on poorly-maintained roads. For standard tires under $200 each, the plan rarely earns its premium across the ownership window.

The legal document proving vehicle ownership. Branded titles (salvage, rebuilt, flood) drop value 30-50%.

A car title is the legal document showing ownership. Title status types: (1) Clean — no significant damage or insurance writeoff history. (2) Salvage — declared a total loss by an insurance company; cannot legally drive on public roads in salvage status. (3) Rebuilt — was salvage, then repaired and re-inspected; legal to drive but typically worth 30-50% less than equivalent clean-title car. (4) Branded — has a permanent disclosure (flood, hail, lemon law buyback). Always pull a Carfax/AutoCheck before buying a used car to verify title status — sellers occasionally try to "wash" branded titles by retitling in lax states.

State DMV fee to register the title in your name. Real, non-negotiable.

The title fee is a state DMV charge to issue a new title in your name. Typical cost: $50-$200, varies by state. This is a real government fee — non-negotiable, dealers don't profit from it, and you'd pay it whether you bought from a dealer or private party. Title fees should appear on the OTD breakdown and match your state's standard rate.

Illegally moving a [branded title](/glossary/title) vehicle through a state with lax titling rules to "wash" the brand off. Federal fraud.

Title washing is the illegal practice of moving a vehicle with a branded title (salvage, flood, lemon, buyback) through a state with weaker title-branding rules to obtain a clean title. Common laundering states historically: Alabama, Georgia, Tennessee, parts of the Carolinas — though all 50 states now participate in NMVTIS (National Motor Vehicle Title Information System), which tracks brands across state lines. A NMVTIS report ($3-$10 from approved providers like VinAudit, ClearVin) catches almost all title-washed vehicles even when Carfax misses it. If a used-car deal looks suspiciously cheap or the title shows multiple state transfers in a short window, pull a NMVTIS report before signing. Buying a title-washed car is legal for the unwitting buyer but kills resale value when discovered.

A car you sell to the dealer as part of a new-car deal. Negotiate separately.

A trade-in is a vehicle you sell to the dealer as part of a new-car purchase. Dealers often "undervalue" the trade to subsidize a "great" deal on the new car — total profit unchanged, just shifted between the two transactions. Always negotiate the new-car price separately from the trade. Get a written Carmax/Carvana/Vroom offer first as your floor; if the dealer can't beat it, sell to Carmax instead.

A model variant with specific feature set. Affects price by $2k-$15k+ on the same base model.

A trim level is a feature configuration of a specific model — same engine and platform, different equipment. Example: Honda Civic comes in LX, Sport, EX, EX-L, Touring, Si trims. Each trim adds features (heated seats, sunroof, larger wheels, advanced safety tech) and price. The trim level determines MSRP and resale value. Always research trim differences before shopping — a "Honda Civic" can be $24k or $34k depending on trim, and the trim ladder isn't always linear (sometimes EX-L is a better value than Touring).

When the salesperson "turns you over" to a more senior closer to overcome objections. Standard escalation tactic — expect 2-3 closers before signing.

A "T.O." or "turn over" is when the salesperson hands you off to a senior closer (sales manager, finance director, or general manager) because you've resisted their best offer. The closer is more experienced at objection handling and has more authority to drop the price or throw in concessions. Standard dealership flow: salesperson → sales manager T.O. → desk manager T.O. → F&I manager (who tries to claw back the discount with back-end products). Each T.O. is intentional pressure architecture — the buyer gets passed up the chain with the implication that the next person is "doing you a favor" by even talking to you. Defense: stay polite, repeat your number, and treat each T.O. as confirmation that your number is closer to the dealer's floor than they want to admit. Set a hard time limit before walking in (90 minutes max) and stick to it.

Owing more on your car loan than the car is worth.

You're underwater (or have negative equity) when your loan balance exceeds the car's current value. Common in years 1-2 of a high-finance loan with little down payment. If you trade in an underwater car, the dealer rolls the negative equity into the new loan ("you owe $25k on a car worth $20k, we'll add the $5k to your new loan"). This compounds the problem. GAP insurance protects against negative equity if your car is totaled.

A 17-character unique ID for every vehicle. Required for title, insurance, and history reports.

The Vehicle Identification Number is a 17-character code (using letters A-Z except I, O, Q, and digits 0-9) uniquely assigned to every vehicle manufactured after 1981. The VIN encodes manufacturer, model year, plant, vehicle type, and a unique serial number. Locations: door jamb sticker (driver side), windshield bottom (driver side), and the title/registration. Use the VIN to pull a Carfax or AutoCheck history report, check NHTSA recalls (free at nhtsa.gov), and verify the vehicle matches what the dealer claims (year/make/trim).

A $20 acid stencil dealers charge $295-$595 for. Refuse.

VIN etching is when the dealer acid-etches your Vehicle Identification Number onto your windshield and side windows, claiming it deters theft. Real dealer cost: $20 (a DIY kit on Amazon). Typical charge: $295-$595. Insurance discounts for VIN etching are usually $25-$50/year — well below the dealer markup. Always refuse this in F&I; you can buy the kit yourself if you really want it.

A new-car warranty with specific coverage terms and exclusions.

A limited warranty covers defects in materials and workmanship for a specified time and mileage, with exclusions (wear items, damage from misuse, etc.). New cars come with a bumper-to-bumper warranty (typically 3 years/36k miles) and a powertrain warranty (typically 5 years/60k miles, sometimes 10 years/100k). "Limited" means there are exclusions — read the warranty booklet. Federal law (Magnuson-Moss) requires written warranties to be available before purchase.

The condition standard a leased vehicle is graded against at turn-in. "Excess wear" charges can run $1,500-$4,000.

Wear and tear is the condition standard your leased vehicle is inspected against when you return it at lease end. The lease contract defines "normal" wear (small scratches under a credit card, tire wear within tread limits, interior wear consistent with mileage) and "excess" wear (dents larger than a quarter, cracked windshields, missing keys, smoke damage, curb-rashed wheels). Excess wear charges typically run $1,500-$4,000 at turn-in. Defenses: (1) buy a wear-and-tear protection plan from the captive lender at signing if you have kids/dogs (cheaper than paying the bills), (2) fix obvious damage yourself before turn-in (windshield replacement is $300 vs. $800 from the lessor), (3) request a third-party independent inspection if the lessor's inspector flags items you dispute.
