Guy Martin has passion: passion for engines, mechanics and, most of all, speed. He's one of the Isle of Man TT's most popular competitors but, away from the media glare, this programme offers a snapshot of some of his favourite things: motorbike racing, engines, MOTs, Radio 4 and his day job as a truck mechanic. Nothing else gives Guy quite as much satisfaction as an immaculately presented toolbox; in fact he seems happiest when surrounded by spanners and grease. The programme meets him hard at work as a lorry mechanic, a job he's cycled to every day since he was 12 years old. He admits he'd choose a day at work over an all-expenses-paid trip to Las Vegas.
