Lenders are more likely to give a car loan to a buyer who they have a relationship with. If you’ve had a car loan in the past and made your payments on time, that lender knows that you’re a responsible car buyer and might offer you a loan or interest rate that other lenders won’t. This holds true with other lines of credit, like a mortgage or a credit card. When you’re shopping for a car loan, make sure to check with every lender that you have borrowed from in the past. Since they already know you, they will see you as less of a risk and give you a lower interest rate on your car loan.
