Car dealers buy a lot of stock at car acutions and mark it up. Auctions such as the Baltimore Car Auctions in this video happen all over the country and if you can find them or better again if you go to a government auction selling repossessed cars, government surplus vehicles and goods, you can walk away with a really good used car at a steal (legally of course!)
There are services that provide comprehensive auction listings to give you the best opportunity of finding the right vehicle or property at the right price. Some of these services cost a few dollars but you can get a free trial of one of the best services available here.
