Right now, good mortgage rates for a 15-year fixed loan start in the 5% range, while good rates for a 30-year mortgage generally start in the 6% range. For used vehicles, the average interest rate can range from 3.61% with Super Prime to 19.87% for Deep Subprime. If you can get a rate lower than 6% for a used car, this is likely to be considered a good APR. The actual interest rates you may qualify for vary depending on your credit rating, the term of the loan, the type of vehicle you're financing, and more.
When buying a car, one of the first considerations is probably how you'll pay for it. If you have a loan for new or used cars in the future, it's worth researching what types of interest rates are available to you.
