A car loan that starts at $12,000 can quietly turn into a $25,000 obligation before the engine ever needs major work.
That math is at the center of how Credit Acceptance Corporation, one of the largest subprime auto lenders in the country, builds its business.
The company specializes in loans to buyers with damaged or thin credit, then relies on a nationwide network of roughly 12,000 independent dealers to originate them.
The pitch to borrowers is simple: get approved and drive away, even with a 550 credit score or a recent repossession.
Many of these loans carry annual percentage rates above 20%, and some stretch past 24% depending on the state.
On a $15,000 used car financed over six years, that rate can add $10,000 or more in interest alone.
Dealers have their own incentive to push these contracts.
Credit Acceptance typically advances the dealer close to the full sale price upfront, then lets the dealer share in the profit as the borrower pays.
That structure, disclosed in the company's own SEC filings, means a dealership can book most of its money on day one while the buyer carries years of payments on a vehicle that may be worth far less than the loan balance.
Borrowers who fall behind face repossession, but because the car depreciates faster than the loan balance drops, they can still owe thousands after the vehicle is gone.
That leftover "deficiency balance" often gets sold to collectors and can follow a borrower for years, making the next car loan even harder to get.
Consumer advocates have pushed back for over a decade.
In Massachusetts, the attorney general sued Credit Acceptance in 2020, alleging the company made loans it knew borrowers couldn't repay.
The state Supreme Court ruled in 2024 that the case could move forward, a decision that could reshape how subprime lenders operate there.
Credit Acceptance has denied wrongdoing and said its loans help people who would otherwise be shut out of the market.
For anyone shopping right now, the practical takeaway is to read the APR before the monthly payment.
A $400 payment sounds manageable until you realize $250 of it is interest.
Buyers should also check the total of payments box, get a preapproval from a credit union, and walk away if the dealer won't show the full contract before signing.
Federal law gives you the right to see those numbers before you commit.
If you're already in one of these loans, refinancing isn't easy but it isn't impossible.
Paying down the balance for 12 to 18 months and adding a co-signer with stronger credit can open doors at banks and credit unions that ignore Credit Acceptance's dealer network entirely. **Our take:** Subprime lending isn't going away, and plenty of people genuinely need a car to get to work.
But a 20% rate on a depreciating asset is less a lifeline than a treadmill.
Final Thoughts
If a deal only works when you don't read the fine print, it probably doesn't work.
