Death Race 2000 is a film set in a semi futuristic world of image over substance that follows an edition of the annual "Transcontinental Road Race" a US spanning race where bonus points for vehicular manslaughter is not only encouraged but necessary in order to win.
Much like the Batmobile in the original Batman TV series,the iconic cars in the film are all standard production cars with cosmetic alterations made(i.e. Frankenstein's car is a Corvette and Joe Viterbo's a Mustang).Similarly to the Batmobile they have become collectors items that have been sold for significantly more than the actual value.
