How does Motrix work?

You tell Motrix the car you want. We contact multiple dealers for you — by email, voicemail and web form — strip every junk fee, and negotiate your out-the-door price in writing. You approve the final number and sign. You never sit across from a salesperson.

What does Motrix cost, and when do I pay?

$0 upfront. You only pay when Motrix lands you a deal you actually sign — $399 for the Deal tier (done-for-you), $799 for Pro (a dedicated human on your deal), or $1,499 for founder-led Concierge. If it does not close a deal you sign, you pay nothing.

Do I have to talk to the dealer at all?

Never. Motrix handles all communication. The only thing you sign is the final contract.

How long does it take?

It is dealer-paced. Across Motrix deals to date the median first written quote arrives in about three days, and deals close over the following one to four weeks. Outreach starts right after your brief is filed and every dealer is worked in parallel.

Does this work for used cars too?

Yes. Motrix works for new, used, and CPO vehicles. Used car negotiations use different tactics — we focus on vehicle history, condition-based pricing, and market comparables rather than MSRP.

What if I have a trade-in?

Enter your license plate number in the brief. We automatically pull your vehicle's value from KBB, Carvana, and CarMax. We negotiate your new car price first, then your trade separately.

Is Motrix a car broker?

No. Motrix is a negotiation facilitation service. We're not a licensed dealer or broker — we're an AI agent that negotiates on your behalf. You make every final decision.

What does Motrix actually do?

Motrix is an autonomous AI agent that contacts car dealers on your behalf and negotiates the entire deal. You submit a brief about the vehicle you want, and the agent handles every dealer interaction — emails, SMS, fee disputes, price counter-offers — until it surfaces a final deal for you to review and sign. You never have to talk to a dealer.

Is Motrix a car broker or dealer?

No. Motrix is a negotiation facilitation service. We're not a licensed dealer or broker. We act as an AI agent representing the buyer's interests. The buyer makes every final decision and signs the contract directly with the dealer.

How does $0 until you sign actually work?

On every paid tier (Deal $399, Pro $799, Concierge $1,499), you pay nothing upfront. The fee only applies if you choose to sign the contract Motrix brings back. If we can't find a deal that works, you pay nothing. 30-minute money-back window after purchase for any reason.

Can I use Motrix for used cars?

Yes. Motrix handles new, used, certified pre-owned, and lease deals. The fee structures and negotiation tactics adapt to the vehicle type — the brief flow asks which condition you want.

What's in the Concierge tier?

Concierge is founder-led negotiation. Founder Jimmy Sturdivent personally handles every step from your first inquiry to your signed contract, with AI agents working alongside. Includes trade-in coordination, financing review, insurance shopping, and delivery logistics. 24-hour SLA on every touchpoint. Concierge is $1,499 and is the one tier paid to start, because the founder personally runs it.

Upside-Down: How to Buy Your Next Car When You Still Owe On Your Current One

You owe $28,000 on a car worth $22,000. The dealer types your numbers into the desk machine, looks up, and smiles. "Good news — we will pay off your trade." Six thousand dollars of negative equity disappears from the conversation. It does not disappear from your finances. It gets rolled into the new loan at 7 percent APR for 72 months, and you sign a contract that puts you deeper underwater on day one than you were on the trade you just got rid of.

This is the most expensive seat in the dealership. It is also the most common — by 2026, roughly one in four trade-ins arrives with negative equity, and the average shortfall is just under $7,000. The buyers who get hurt worst are the ones who do not know they are negotiating from a hole.

What negative equity actually is

Negative equity (also called being underwater) is the gap between your loan pay-off and the current market value of the vehicle. Pay-off minus trade value. If pay-off is bigger, you are upside-down.

It accumulates from four sources, usually stacked.

The depreciation curve. A new car loses 20 to 30 percent of its value in the first 12 months. A $40,000 vehicle is worth $30,000 a year later. If you financed 100 percent of the price plus tax and fees, your loan balance after 12 months is roughly $34,500. You are $4,500 underwater on month thirteen — through no fault of your own. Depreciation is doing the work.

The long loan term. Seventy-two and eighty-four month auto loans are now the majority of new-car financing in the United States. Longer terms keep monthly payments accessible, but they slow principal payoff to a crawl. On a 72-month loan, you are still upside-down at month 30. On an 84-month loan, you are upside-down until month 42.

The rolled-in negative equity from the previous trade. This is how the position compounds. Buyer trades a car with $4,000 of negative equity into a $35,000 purchase financed at 100 percent. The new loan is $39,000. The new car is now worth $35,000 the moment it leaves the lot — so the buyer is $4,000 underwater before depreciation even starts.

The aggressive F&I add-ons. Extended warranty for $2,500, GAP for $900, paint protection for $700, VIN etching for $295. All of it rolled into the loan. Each add-on extends the upside-down period by months.

Why rolling negative equity is a trap

The seductive part is that rolling negative equity erases the awkward number from the deal. You drive away with no out-of-pocket gap payment. The math, though, is brutal.

Suppose you owe $28,000 on a car worth $22,000 — $6,000 underwater — and you finance a new $40,000 vehicle. The dealer rolls the $6,000 into the new loan. Your principal is now $46,000, financed at 7 percent APR over 72 months.

That extra $6,000 of rolled negative equity costs you:

$1,330 in additional interest over the 72-month loan life
An extra $99 per month in payment
An additional 18 to 24 months of being upside-down on the new car
A loan-to-value ratio of roughly 115 percent on day one — which forces you into the dealer's subprime financing tier even if your credit is excellent

You are not solving the negative equity. You are paying interest on it for six years and dragging it forward into the next deal. The shortfall becomes a permanent feature of your auto-loan life, like an injury that never quite heals.

"We will pay off your trade" — what the line actually means

Every car ad uses some version of this phrase. "We will pay off your trade, no matter how much you owe." It is a true statement and a fully misleading one at the same time.

The dealer does pay off your trade — by writing a check to your old lender for the full pay-off amount. They also take possession of the car at the value of the trade-in they negotiated. The difference — the negative equity — gets added to the new loan as a line item called "prior loan balance" or "pay-off from trade" on the contract.

There is no magic. There is just paperwork. Your $6,000 shortfall becomes $6,000 of additional financed principal on the new vehicle, plus interest, plus extension of the underwater period.

The defensive read on the line: "we will pay off your trade" means "we will move your debt onto the new car." It does not mean "we will absorb the loss." Dealers do not absorb losses on trades. They pass them to the buyer in a form that is mathematically harder to see.

The four better paths

For every negative equity position, there is a path that beats rolling it into a new loan. The right path depends on the size of the shortfall, the urgency of the purchase, and the buyer's cash situation.

Path 1: Pay the gap in cash. Pure math winner if you have the cash. Pay off $6,000 today, trade the car clean for $22,000, and finance a new car at a normal loan-to-value ratio. You eliminate the $1,330 of compounding interest, avoid the subprime tier bump, and start the next loan above water on day one. Hardest emotionally — nobody likes writing a five-figure check for a car they no longer own — but cheapest financially.

Path 2: Delay the purchase. If the current car runs and you can wait 6 to 12 months, accelerated principal payments combined with a slowed depreciation curve typically erase $3,000 to $5,000 of negative equity. Add $200 a month in extra principal and most buyers cross back into positive equity within a year. The delay is free.

Path 3: Refinance the current loan. If your APR is high (subprime, or financed when rates were elevated) and your credit has improved, refinancing the existing loan at a lower rate redirects more of each monthly payment to principal. The car is still depreciating, but principal payoff accelerates. Two to four points of APR reduction can pull a buyer above water 8 to 14 months earlier than the original schedule.

Path 4: Sell privately and bring the gap. Private-party sale almost always nets $1,500 to $3,000 more than the dealer's trade offer. On a $22,000 trade, a $24,500 private sale shrinks the negative equity from $6,000 to $3,500. Combine with a smaller out-of-pocket gap payment and you arrive at the new dealer clean. Time cost: 2 to 4 weeks of listing, photos, and tire-kicker calls.

The five-step evaluation framework

Before agreeing to roll any negative equity, run this check.

Step 1: Pull your exact pay-off in writing. Call your lender or use their app. Get the 10-day pay-off — principal plus accrued interest through a specific date. Do not use the monthly statement balance and do not let the dealer type in their own number. Print the lender quote and bring it.

Step 2: Get three written trade values. Drive through Carmax for the in-person inspection offer. Pull online instant offers from Carvana and a third source (CarGurus, Vroom, your bank's trade tool). The highest of the three is your true trade floor — anything the dealer quotes below it is a discount on top of the negative equity hit.

Step 3: Compute the actual shortfall. Pay-off minus highest written trade offer. This is your negative equity. If it is under $2,000 or under 5 percent of the new car price, rolling it forward is acceptable. Above $5,000 or 10 percent of the new car price, you have a structural problem that rolling does not fix.

Step 4: Run the rolled-loan damage. Take the negative equity, multiply by your new APR, divide by 12, multiply by the loan term in months. That is the additional interest you pay for the privilege of rolling. On $6,000 at 7 percent over 72 months: $6,000 x 0.07 x 6 = $2,520, of which about $1,330 is straight interest above what amortization would catch up.

Step 5: Compare to the three alternative paths. Cash gap today, delay 6 months, refinance current loan. If any of the three nets a better total cost, take it instead of rolling.

When rolling is acceptable

There is a narrow case where rolling negative equity into the new loan is the right move. It looks like this:

Negative equity is under $3,000
The new car has a strong residual value (Toyota, Honda, Subaru hold value)
You will keep the new car at least 6 years (long enough for the rolled debt to amortize out)
Your APR on the new loan is under 5 percent (low enough that interest on the rolled gap is small)
You did not finance any extended warranty or paint protection add-ons that stack the new loan further

Under those conditions, the additional interest cost on the rolled gap is $300 to $600 over the loan life — annoying, but tolerable.

Outside those conditions — high APR, low residual, short ownership horizon, or large shortfall — rolling is the most expensive available option. Almost any other path costs less.

The bottom line

Negative equity is a math problem with three honest answers and one seductive lie. The honest answers — pay the gap, wait it out, refinance the current loan — all cost less over a five-year window than rolling the shortfall into a new car. The seductive lie — "we will pay off your trade" — moves the debt into a longer term at a higher rate and extends the underwater position into the next decade.

Pull the pay-off in writing. Get three trade values. Run the rolled-loan damage. Compare to the alternatives. Sign the new loan only if rolling is genuinely the cheapest path forward — which, for almost every buyer, it is not.
