Did you somehow get the idea that this is a charity event for the car hobby and not a commercial enterprise? Have you not looked at the guys on the podium to see what sort of people they are? More fair?
I have been to that auction a number of times and I must say that it is the lowest class , most crass event I have ever been to. You have a pile of blue collar heroes who have money but not sophistication being suckered by a bunch of carnies with all the niceties of a loan shark transaction. It is funny if nothing else and somewhat boring overall to watch but the tempo is pretty cool. I would not go to a dealer to buy a car with my sister because I find it tedious, to watch an infomercial on TV for 4 days or worse - to be there as a non bidder - has all of the excitement of watching someone else play a video game.
I will give them their due. B-J are the best I have ever seen at parting the rubes from their money for sure and they are the undisputed champs at turning what should be a business transaction into an emotional impulse buy for huge money. I myself wish I was so good at selling high ticket items in the IT world. They do in seconds what takes me months. They are the masters of timing and process flow and I take my hat off to them.
