Guy plans to create a racing version of a Piaggio Ape - the tiny three-wheeled vehicles that are ubiquitous across Italy. While these vehicles were never designed with motorsport in mind, he discovers a racing scene based around them has sprung up in Italy, with drivers customising their Apes with motorcycle engines and improved suspension.

Guy Martin transforms a vintage and extremely rare East German Trabant, which proves to be the slowest vehicle he has ever worked on. With a little advice from one of Europe's top Trabant racers, Guy enters his creation in a historic classic car race at Brands Hatch.
