If you go to KBB.com (Kelly Blue Book) and look up the wholesale price of your car, that includes listing mileage, options and condition, Carmax dealers will give you that price on the spot after a brief test drive. I had to sell two cars when my parents passed away and I got exactly the price on both to the penny. Carmax locations are all over the country, this takes out the problems associated with Craig's List, private ads in the newspaper, etc. The closest to TV is in Sanford, about 90 minutes east of here, there is an Automax in Ocala, but I don't know if they operate the same.
