Game show 6 weeks long. 3 contestants took their own cars on the stage and sat in them . The show had 4 cars on the other side of the set which included sports/4x4/saloon etc and Claudia winkleman asked the contestants questions about themselves which they had to answer without hinting which car they would like to trade up to. The audience had keypads and had to press a button 1-4 indicating which car they thought the contestant would like.The audience had to match up the chosen car to what they thought the contestant would choose and once revealed by the contestant if they had the most hits they won.Whoever won had to give their car and take the chosen car hence trade up.The cars were not brand new but worth at least twice the amount of the contestants and came with a years insurance and tax if i can remember right. Wasn't a great show for the audience/people at home i dont think except for the winners.
