Just from watching the TV show on Discovery it seems like the guy has a bunch of junk on his lot. I watched one show where the guy was there to pick the car up, and it wouldn't start, and the guy had his mechanics scrambling trying to get the car to run, and I've seen shows where someone will buy a car, and he'll get a call that the car broke down on the way home, or the guy got the car home, and isn't happy with the car. I don't know why if you're a legitimate businessman with a high end car lot why you'd put stuff like that on your TV show.
I love how he uses his wife, who looks like she was rode hard and put away wet, as his closer. He's always bragging that men can't resist his wife's beauty, and that makes her a great slaesperson. His wife wouldn't be considered beautiful up in Michigan, and they're down in South Beach. Give me a break.
As far as Barrett-Jackson goes they get ten of thousands of applications for every auction they have, I believe four a year, and they sift through the applicants, and pick the best of the best couple thousand for every auction. Barrett-Jackson in the cream of the crop. Especially the Scottsdale, AZ auction which is held every January. There are guys that have businesses where they will work on restoring 4 or 5 cars all year to get ready for the January Barrett-Jackson auction in Scottsdale, and the profit they make off of those 4 or 5 guys is how they make a living. There's a guy, Amos Minter, out of Texas that only restores 1955 through 1957 Ford Thunderbirds, and he shows up with about a half dozen every year, and every one will sell for a $100,000 plus. There's another guy, Kurt Tanner, out of California that only restores Austin Healeys, and he will show up every year with about a half dozen Austins, and they will all sell for $100,000 plus.
