CarMax's appraisal process is fast and free. Your appraisal can take as little as 30 minutes and you're welcome to watch while you wait. There is no obligation—we'll buy your car even if you don't buy ours. There is also no appointment needed. Bring your car in for an appraisal any time we're open. Our appraisers are specially trained to evaluate the cars we buy. Your written offer is good for seven days at any CarMax location, and if you sell us your car, you'll receive a bank draft on the spot! Check out www.carmax.com for more information.
