I caught a couple of episodes. IMO, I think those guys are tools, but I guess that's the entertainment value they bring to the table.
They might have a tough time selling that RR. I caught an episode of Mecum Auction where they sold a 71 383 #'s matching RR for around $23k. I can't remember what engine the one in Car Guys had though.
The Mecum auctions aren't high end like Barrett-Jackson either. The majority of the cars in the Mecum auctions are cars that the average person could buy.
