According to Wikipedia, there are over 250 million registered vehicles in the United States; this includes cars, SUVs, pick-up trucks, and motorcycles. About 8 million of these were bought new or used from dealerships in the last year, and many of these buyers needed car loans.
Credit determines Lease Approval.

An auto loan is a type of secure loan worth the amount of the car in question. It is paid back in monthly installments; the payment terms are often negotiated by the "useful" life of the vehicle, or its estimated future blue book value. Auto loans are either direct or indirect.

A direct loan will come straight from the bank to you, and an indirect loan is when a dealership acts an intermediary between a bank (usually theirs) and you. Most auto loans have high interest rates regardless of your credit score.
Interest rates and your credit report
 

Credit deterimines Interest Rates

Your interest rate is affected by your credit report. You need to review your credit report before you apply for a loan. If there are mistakes or discrepancies on your credit report, notify the credit bureau or benefit from our credit repair services.  A credit repair expert will evaluate your report and help you obtain a healthy, accurate credit report.
 
If you have missed payments on your bills, credit cards, or mortgage, it will show on your credit report. It may be possible to remove these notations if you have made the accounts current by paying all past due balances. Your best car loan and your best interest rate will be determined by your credit history and credit score. Be prepared and boost your credit before applying for a car loan.
