Most people start car shopping on the lot. By then, the part that decides your rate is already done. It's your file.
The dealership's finance office is going to pull your credit, read it, and sort you into a tier. Everything that happens after that (the rate, the down payment they ask for, whether a lender says yes at all) follows from what's on the report that day. So the real work happens in the weeks before you go, not in the finance office.
The stakes are real money. In Experian's second-quarter 2026 data, the average new-car rate was 4.41% for borrowers in the top credit tier and 13.52% for subprime borrowers. On used cars the gap ran from 6.29% to 19.10%. Same car, same price, very different loan.
Here's the order I'd work in.
What credit score do auto lenders actually use?
Many auto lenders pull a FICO Auto Score, an industry version of FICO that runs from 250 to 900 instead of the 300 to 850 range you see in most apps. Others use a general FICO score or VantageScore, and you usually can't know which one until the lender pulls it.
That's why the number on your phone and the number the dealer quotes rarely match. It's not that one of them is wrong. They're different models reading the same file.
So stop chasing a single number. Every one of those models reads the same accounts, balances, and payment history underneath. Fix the file and every score moves with it. I broke down how dealerships group buyers by score in my article on buying a car with bad credit.
What should I fix on my credit report before applying for a car loan?
Start with anything that's reporting wrong: a late payment you didn't make, an account that isn't yours, a paid-off loan still showing a balance. The Fair Credit Reporting Act lets you challenge information that's inaccurate, unverifiable, or outdated, and the bureaus generally get 30 days to investigate, so this has to come first.
Pull all three reports free at AnnualCreditReport.com and read them line by line. Not the summary. The account detail, where the dates and balances live.
Here's the part people don't want to hear. If a late payment is accurate, you generally can't dispute it off. Accurate history stays. What you control is everything that's wrong, plus how the rest of the file looks next to it. If something on your report doesn't match your life, here's what to do about items that aren't yours.
How do I lower my credit card utilization before I apply?
Pay your card balances down before each statement closes, not before the due date. The balance on your statement is the one that gets reported to the bureaus, so a card you pay in full every month still reports high if the statement cut while the balance was up.
This is the fastest thing on the list. No disputes, no waiting on a bureau. One or two statement cycles and it shows up. The 30% number most people aim for isn't the target, either. Here's the real number.
What do auto lenders look at besides my credit score?
Two numbers matter almost as much as your score: how big the payment is next to your income, and how big the loan is next to the car's value. A bigger down payment improves both.
Payment-to-income. This is your monthly car payment divided by your monthly income. The CFPB found that for loans made from 2018 through 2022, the average car payment took about 7.9% of a non-military borrower's income. Lenders set their own limits, so run your own number before they do.
Loan-to-value. This is the loan amount divided by what the car is actually worth. Roll the negative equity from your current car into the new loan and you're often borrowing more than the new car is worth. Lenders read that as more risk, and it follows you into the rate.
A down payment shrinks the loan, which lowers both numbers at once. If you're borderline on credit, cash down is the lever you control today.
Should I get preapproved before I go to the dealership?
Yes. The CFPB recommends getting preapproval offers from several lenders, like your bank or a credit union, before you shop, so you walk in with a real rate to compare against.
Here's why it matters. When a dealer arranges your financing, the lender quotes the dealer a rate called the buy rate. The dealer is allowed to offer you a higher rate, the contract rate, and the lender shares that extra interest with the dealer. That's how dealer financing works. It's also why the first rate you're offered isn't the only rate available.
With a preapproval in hand, the dealer has to beat your number or lose the financing. Settle the price of the car first, then talk financing, so a lower rate doesn't get traded for a higher price.
How long can I shop for a car loan without hurting my score?
Scoring models count several auto loan inquiries made close together as a single inquiry. Depending on the model, that window runs from 14 to 45 days, so do all of your rate shopping inside two weeks and you're covered under every model.
Newer FICO versions use a 45-day window. Older FICO versions and VantageScore use 14 days. Since you don't know which one a lender runs, two weeks is the safe stretch. Shopping one car loan is normal borrower behavior, and the models are built to allow it. More on how inquiries really work.
Can I get a car loan with a repossession on my report?
Yes, but every auto lender will see it and price the loan for it. An accurate repossession generally stays on your report for seven years from the date of first delinquency, so the work is making sure it's reported correctly and making everything around it stronger.
Read the repo line by line. Wrong dates, a wrong balance after the sale, or an account that shows open when it's closed are all worth challenging. And if you returned the car yourself, know that a voluntary surrender is still reported as a repossession.
If it's accurate, it stays. Your answer then is a bigger down payment, a lower payment-to-income ratio, and a clean run of on-time payments on everything you have open now.
The order I'd do it in
- Pull all three reports at AnnualCreditReport.com and read the account detail line by line.
- Challenge anything inaccurate at least a month before you plan to apply.
- Pay your cards down before the statements close for one or two cycles.
- Run your numbers: the payment you can carry next to your income, and the down payment you can put in.
- Get two or three preapprovals from a bank or credit union.
- Do all of your rate shopping inside two weeks.
- Settle the price of the car before you talk financing.
