Yes, it is indeed possible to sell a car to CarMax even if there is still a loan on it. CarMax can help you through the process of selling a vehicle that has an outstanding loan. When you bring your car to a CarMax location for an appraisal, they will assess its value and provide you with a cash offer. If you owe money on the loan, the offer from CarMax will be used to pay off the remaining balance. If the offer exceeds the loan amount, you can receive the difference in cash. If the loan balance is higher than what CarMax offers, you will need to pay the difference in order to complete the sale. For further details regarding the process, it is recommended to visit the current CarMax website, where additional information can be found.
