The Stig
The presenters, based at Knockhill Racing Circuit in Fife, were set the task of building a Caterham Seven Kit car from scratch and drive past the starting line, faster than the time it would take The Stig to reach the track from the Caterham showroom in Caterham using a pre-built Caterham Seven Kit car. The presenters won the challenge because The Stig was stopped by the traffic police just 3 miles from the finish. (The Stig "exercised his right to remain silent," and was taken into custody.)
