Dealer junk fees, explained.
Every fee dealerships add to your contract — what it is, why they charge it, and how to refuse it.
Dealerships layer 6-10 line items on top of MSRP to inflate the final price. Some are negotiable. Some are pure markup. Two are actually legitimate captive lender charges that dealers will tell you aren’t. Here’s every fee, what it is, and how to handle it.

01Documentation Fee
What it is
Paperwork processing fee. Most states have a statutory legal max.
Dealer's claim
"Required for title and registration paperwork."
Reality
Some states cap this by statute (California caps it at $85; anything above a legal cap is pure markup). Many states, Florida included, set no cap at all, which is why Florida doc fees run among the highest in the country.
How to handle
Look up your state's legal cap before signing. Refuse anything above it. If the dealer claims the fee is fixed, ask them to point to the state DMV cite — they can't, because it isn't.
02Dealer Market Adjustment / "ADM"
What it is
Pure markup above MSRP, also called "Additional Dealer Markup" or "Market Adjustment".
Dealer's claim
"High demand, low supply pricing."
Reality
Dealers charge ADM when they can and drop it when they can't. Hyundai, Kia, Ford, and Cadillac have publicly disavowed ADM during 2024-2025 — yet dealers still charge it. The same vehicle at the same MSRP carries $0 ADM at some dealers and $5,000 at others in the same metro.
How to handle
Always refuse during off-peak demand. During peak demand on allocation-limited vehicles, shop multiple dealers in your region — some won't charge ADM on the same vehicle. If you're willing to wait 4-6 weeks for a factory order, you can almost always avoid ADM entirely.
03Paint Protection / Ceramic Coating / Sealant
What it is
Wax or polymer sealant applied to exterior paint at the dealership.
Dealer's claim
"Lifetime paint protection."
Reality
A $15 bottle of consumer ceramic coating performs equivalently. Dealer-applied sealants are wax with a marketing brochure, marked up 50-100x over the dealer's actual material cost.
How to handle
Always. If the dealer says "we already applied it," refuse the charge — dealers can't legally bill you for unauthorized work. If you want real ceramic coating, take it to a professional detailer post-purchase for $200-$500.
04Nitrogen Tire Fill
What it is
Nitrogen gas in your tires instead of standard atmospheric air.
Dealer's claim
"Better fuel economy, slower pressure loss, longer tire life."
Reality
Standard atmospheric air is already 78% nitrogen. The 22% additional benefit from pure nitrogen is undetectable in normal driving. Free air is at every gas station. Compressed nitrogen costs the dealer about $2 per fill.
How to handle
Always. If applied, refuse the charge — the green valve caps cost less than the line item charge to install.
05VIN Etching
What it is
Etching your VIN onto the windshield and side windows as anti-theft.
Dealer's claim
"Reduces theft risk and insurance premiums."
Reality
DIY VIN etching kits cost $5-$15 at any auto parts store. Insurance discount for VIN etching is typically $0-$15/year — economically irrelevant compared to the $200-$400 charge.
How to handle
Always. If you actually want VIN etching, buy the kit and do it yourself in twenty minutes. Most thieves don't check windshields.
06Wheel and Tire Protection
What it is
Insurance covering tire and wheel damage from potholes, curbs, road debris.
Dealer's claim
"Protects your investment in expensive wheels and tires."
Reality
Legitimate product but dealer-marked-up 100-300% over what your auto insurance company or a third-party provider would charge for equivalent coverage. Often duplicates coverage you already have through comprehensive auto insurance.
How to handle
Decide separately on your terms. If you want the coverage, decline at the dealer and buy from a third-party provider or your auto insurer for half the price.
07GAP Insurance (dealer markup)
What it is
Guaranteed Auto Protection. Pays the difference between what you owe on the loan and the car's value if the vehicle is totaled.
Dealer's claim
"Required if you're financing a depreciating asset."
Reality
Legitimate product, especially for high-loan-to-value financing. But dealers mark it up 3-5x. Your bank or credit union sells GAP for $200-$400.
How to handle
Decline at the dealer. Buy from your bank within 30-60 days of loan origination. Same coverage, fraction of the price.
08Extended Warranty (dealer markup)
What it is
Service contract covering repairs beyond the manufacturer warranty period.
Dealer's claim
"Peace of mind for the life of the vehicle."
Reality
Legitimate product for certain buyers (high-mileage drivers, complex vehicles outside CPO coverage). But dealer-marked-up 2-3x over what third-party warranty companies charge for equivalent coverage.
How to handle
Decline at the dealer. If you want a warranty, shop CarShield, Endurance, or your manufacturer's online warranty store independently. Compare specific coverage terms, not just monthly price.
09Acquisition Fee
What it is
Captive lender charge on leases. Set by the lender (Honda Financial, Ford Credit, GM Financial, etc.), not the dealer.
Dealer's claim
"Required by the leasing company."
Reality
ACTUALLY LEGITIMATE. The captive lender charges this fee to originate the lease — it's real and shows on the lender's rate sheet. The dealer may stack $100-$300 in markup on top of the captive base. (Source: tier-4 dealer correspondence, Wave 1.5 intel.) Distinct from security deposit, which is separately set by lender guidelines based on credit tier.
How to handle
Verify the base fee against the captive lender's published rate sheet for your specific brand and lease month. Negotiate only the dealer markup, not the base. Don't refuse the entire fee — that's a non-starter; the captive controls it, not the dealer.
10Disposition Fee
What it is
Fee charged at lease termination if you don't buy the leased vehicle.
Dealer's claim
"Covers vehicle inspection, cleaning, and resale prep."
Reality
ACTUALLY LEGITIMATE if specified in your lease contract. Set by lender guidelines — not invented by the dealer. Negotiable only at lease signing, not at lease end.
How to handle
Negotiate the fee out of your lease contract at signing — some captive lenders will waive it as a closing concession. If already signed, you owe it at lease end unless you (a) buy the vehicle, (b) lease another from the same captive (often waived as a loyalty incentive), or (c) transfer the lease.
How Motrix handles all of this
Every line item, contested in writing.
When the dealer’s quote lands, Motrix’s agents audit it line by line. Junk fees get refused with the specific reason. Documentation fees that exceed state cap are pushed back to the legal floor. Market adjustments get refused on principle during off-peak. Paint protection, nitrogen, VIN etching: zeroed. Wheel coverage, GAP, extended warranty: declined at the dealer with a note to buy independently if wanted.
Acquisition and disposition fees are recognized as legitimate captive-lender charges. The agents verify the base fee against the captive’s published rate sheet and only contest the markup the dealer stacked on top. Same approach an experienced buyer would take, scaled to every dealer in your zip code in parallel. You see every refusal in writing before the deal closes.
