Film: Death Race
Price (approx.): $20k
Don’t try this at home: When competing in a life-or-death (mostly death) competition against a group of prison psychopaths, it helps to have a vehicle modified with two M134s, smokescreen, napalm and oil slick for defence, as well as a 6-inch-thick (150 mm) detachable steel plate on the rear called "The Tombstone." Oh, and a cigarette lighter, which is a bit dangerous. Better check some of these modifications with the DVLA to make sure they're street-legal though, eh?
