Frequently Asked Questions
Is a car loan secured or unsecured?
A standard auto loan is a secured loan. The vehicle you are purchasing serves as collateral, and the lender holds the title until the loan is fully repaid. This is why auto loan rates (4.5-8.5% for new cars in 2026) are significantly lower than unsecured personal loan rates (6-36%). If you stop making payments, the lender can repossess the vehicle without going to court in most states.
When would I use a personal loan instead of an auto loan?
An unsecured personal loan makes sense for car purchases in specific situations: buying a very old vehicle (many auto lenders have age or mileage limits and will not finance cars over 10 years old), purchasing from a private seller where auto financing is more complex, buying an inexpensive car where the loan amount is small, or when you want to own the title outright from day one without a lien.
What credit score do I need for a good auto loan rate?
For the best new car auto loan rates (under 5%), you typically need a credit score above 720. Scores of 670-719 get good but not optimal rates. Scores of 580-669 face subprime rates of 9-15%+. Below 580, many direct lenders decline, though buy-here-pay-here dealerships and some credit unions serve this segment at higher rates. A 100-point credit score improvement can reduce your auto loan rate by 3-6 percentage points.
Should I finance through the dealer or get my own auto loan?
Getting pre-approved from your bank or credit union before visiting a dealer gives you negotiating power. Dealership financing can be competitive, especially with manufacturer incentive rates (0-2% APR promotional offers), but dealers also mark up rates they receive from lenders. If the dealer cannot beat your pre-approved rate, use your own financing. Captive finance arms (Ford Motor Credit, Toyota Financial) can be very competitive for new cars.
How does term length affect total auto loan cost?
Longer terms (72-84 months) lower your monthly payment but dramatically increase total interest paid. A $30,000 auto loan at 6.5%: 48-month term = $711/month, $4,134 total interest. 72-month term = $504/month, $6,288 total interest. The 72-month loan saves $207/month but costs $2,154 more overall. Additionally, longer-term loans risk being underwater (owing more than the car is worth) for longer.
