World snooker champion Ronnie O’Sullivan asked Fifth Gear to help him choose a new car to spend his winnings on, so Vicki takes him out onto the track in a Mercedes C63 AMG and a BMW M3. Tiff and Jason put the Mitsubishi Evo X FQ300 and the Subaru Impreza WRX STi head-to-head on the track. Tom tests Ford’s new SUV, the Kuga, by driving it on snow, road and mud. Jonny investigates if cars are worth more as scrap than as a functioning car. Tiff tries out the world’s first underwater car, the Rinspeed Squba, which was inspired by James Bond’s white Lotus Esprit in “The Spy Who Loved Me”.
