The presenters are tasked turning a car into an amphibious vehicle and capturing the public's imagination – Hammond buys a 1983 Volkswagen T3 campervan and turns it into a houseboat, May converts a 1962 Triumph Herald into a sailing craft with a mast and some sails, and Clarkson uses a 1989 Toyota Hilux pick-up truck and plants a huge outboard motor on its back. The trio soon see how their creations fare on the road, before taking them onto the waters of Rudyard Lake near Leek, Staffordshire and crossing two miles of it, where one of the presenters has a sinking feeling about their amphibious car. Meanwhile, Hammond is in Iceland to race a man with powered canoe against a specially prepped 4x4 Tomcat. Stars in a reasonably priced car: Ewan McGregor, Gordan Ramsay.
