Does "Well Bought" mean that the seller got screwed?

IMO, since Ford was the dominant sponsor, it is not surprising that other brands were given less screen time. You don't bite the hand that feeds you.
Also, some of the cars that Craig Jackson said were under the money WERE under the money. There were numerous hot rods, resto mods and some admitedly incorrect retorations, like the yellow Shelby Mustang, that sold for less than what it would have cost to put them together.
The '68 and '69 Camaro resto mods cost the sellers a bunch of money to build, and they both sold for half of that.
As Jay Leno said about himself, being the president of the "More Money than Brains Club", some guys always end up upside down on their pet projects, and get their lunch handed to them. How many time has it been discussed that $100k was invested to restore a car worth $75k?
