CarMax is America's largest used-car retailer and a Fortune 500 company. The corporate entity behind the formation of CarMax was Circuit City Stores, Inc. The first CarMax used-car store opened in September 1993, 1.7 miles (2.7 km) from Circuit City's corporate offices in Richmond, Virginia.
A former employee said this in a review at Indeed website: "In terms of job security at CarMax, I think they are horrible, you never know when your going to get fired and if they don’t like you they will find a reason to fire you!".
