Yes, but there are restrictions. You’re going to have to talk to your lender first and find out how much you still owe, also known as the payoff amount. You may be required to be able to pay off the car to sell it, or your lender may have other specific rules in place.
If your lender gives the okay, you can post a listing for your car. The most important thing you can do is be honest with potential buyers about the loan’s existence—you don’t want to blindside a buyer and have them back out at the last minute.
