The Bullitt Mustang Prototype was created for the 2000 LA Auto Show, and was given the green light for production in the 2001 model year. The concept model differed from the production model in several ways, including the grille, wheels, steering wheel, fuel door, decklid, and rear bumper. The prototype Bullitt sold for $68,150 at a Christie's Auction in 2002. Check out these pictures, then see Timeline: 2001 Mustang.
