Get Pre-Approved Before Shopping
Walk into the dealership with a pre-approval letter. This gives you negotiating power and a baseline rate to compare against dealer offers.
Choose a Shorter Loan Term
48-60 month loans have lower rates than 72-84 month terms. Longer terms mean more interest paid over the life of the loan.
Consider Certified Pre-Owned
CPO vehicles often qualify for new-car rates while costing significantly less. Best of both worlds for rate-conscious buyers.
Make a Larger Down Payment
20% down reduces your loan amount and may qualify you for better rates. It also protects against being underwater on the loan.
