He does have his own resto crew but he likes to do stuff himself as much as he can. I think it was earlier this year he got burned pretty badly when he was working on one of his cars that sprung a big fuel leak and caught on fire. If you watch his videos on his steam cars he goes into so much detail about how they work that it's pretty clear he was personally heavily involved in getting the cars restored and running. Most guys in his position would just have the crew do everything and not bother getting their hands dirty.
