The man who builds F1 cars in his shed

The high-octane world of F1 is constantly trying to push the technical barrier. Teams spend millions of pounds building and developing cars in their squeaky-clean factories. But there's one man doing it by himself, in a shed at the bottom of his garden. With parts scavenged off the internet. His name is Kevin Thomas, and if Top Gear did Blue Peter-style badges, he'd be getting gold.

Most people, when they decide they like Formula One, daydream about what an F1 car would be like to sit in, and possibly drive. But Kevin is not most people. Four years ago, when he saw an F1 car on display in a Renault showroom, he had an epiphany. And decided to build his own. In his shed.
