I love the show myself, actually was in Iowa last month and stopped past there shop. The chick whose name escapes me at the moment was really nice. The guys were on the road.
Anyway they had tons of cool stuff in there including a 1914 un-restored and untouched Indian motorcycle, it had a gas head lamp and everything. As far as their prices go, there was stuff in there that i recognized from the show that wasnt really marked up all that much.. like i remembered them picking it for 35 and it was for sale for 65.. that seems fair to me. I was actually surprised, i figured that the prices were going to be through the roof, they weren't. All the real cool stuff like the old bikes were NFS.
I think a big reason they generally pass up cars is they take up a ton of space, there shop is really quite small. Alot of your guys shops would tower over there shop
