Is this the UK show with Jimmy Carr thats showing or an American version? In the UK ones that I saw the prize was a Mini Cooper. The contestants also had to get an electric shock when they answered a question, drink their own pish, and sit under a pigeon cage and get crapped on. In the final the guy who won (???) had to answer 5 questions, for every one he got right he had to smash in part of the car, After he got the questions right he won the car, complete with smashed mirrors, headlights, windows and doors, spray painted bodywork and slashed seats.
