If the internet is to be believed Guy Martin still holds down a full time job at his local Scania dealer as a vehicle fitter and does all this other stuff in his spare time. Nice story if it is true.
Yep, true, I went to the live interview he did in Sheffield earlier this year (with Suzy Perry) top bloke, even managed to get a quick chat later one to one, he was grasping a big mug of Yorkshire tea and still had mucky fingernails and oily hands
