Are Any Of These Guys Handy?
The best segments of the old show were when they got old junkers and modified them in ridiculous ways. There was a huge mechanical aspect to the show before.
James May's Camper/Caravan fabricated out of aluminum siding comes to mind. Or the ambulance/hurst competition. Or how about the Reliant Robbin space shuttle. I know they probably got a lot of off-camera help. But they were all fully qualified mechanics.
