If your goal is to minimize the total cost of the car loan, the best strategy is usually to get financing lined up before you walk into the dealership.
A good approach
- Check your credit first. Your credit score/history, income, existing debts, down payment, loan term, and whether the car is new or used can all affect your rate.
- Get 2–4 preapprovals. Check a credit union, your bank, and one or two online lenders. A preapproval tells you the APR, loan amount, and term you're actually being offered rather than an advertised "starting at" rate. The CFPB specifically recommends getting financing offers before visiting the dealer.
- Do your loan shopping in a short window. Auto-loan inquiries made within roughly 14–45 days are generally treated as a single inquiry for credit-scoring purposes, depending on the scoring model.
- Take the lowest legitimate preapproval to the dealer. Tell the dealer you already have financing and ask whether they can beat the APR. Dealer financing is negotiable, and dealers can sometimes add a markup to the lender's "buy rate."
- Compare APR—not just the monthly payment. A 72- or 84-month loan can make a car look affordable because the monthly payment is lower, but you'll generally pay more interest overall. Compare:
- APR
- loan term
- total interest
- total amount financed
- fees
- prepayment penalty, if any
- Negotiate the car price separately from financing. Ideally, settle the out-the-door price of the car first, then negotiate the financing. Otherwise, a dealer can make a deal look attractive through the monthly payment while changing the price, term, or financing cost.
One important trick
Don't assume the dealer's promotional financing is automatically worse. Manufacturers sometimes offer unusually low APR promotions to buyers with strong credit. Compare the manufacturer's offer against your outside preapproval rather than dismissing either one.
Example: On a $30,000 loan, a 6% APR for 60 months costs about $4,800 in interest, while 9% costs about $7,400—roughly $2,600 more.
If you tell me (1) your approximate credit score, (2) new or used car, (3) car price/budget, (4) down payment, and (5) desired loan length, I can help you figure out what APR range to shop for and how to structure the loan.
