While there is no fixed minimum rule, your credit score is a deciding factor for your loan terms and interest rate.
Before shopping for your car loan, review your credit report, check for errors, and evaluate if you are ready.
Having a good credit score above 661 can get you a good loan with lower interest rates.
If your score is lower than that, try and improve it first so you save money and get better terms on your loan.
While a lower credit score won't hurt your chances of getting a loan, you may end up paying higher interest rates.
If you can wait, work on areas that need improvement. Fix the problems that are lowering your score.
Shop around and compare rates between lenders. Pick the loan that offers the best rate and terms.
Save enough money for a down payment and consider a co-signer to improve your odds of loan approval.
When you finally close in on a deal, make your monthly payments on time to ensure your score doesn't take a hit.
