I pretty much agree, but would add 2 sellers. Somebody that's upgrading. Someone selling so he can afford to build something different. A lot of guys can't afford to keep one car / truck / motor/ etc and build a 2nd one. Much of the time you have to catch this seller at the right time of his new rebuild.
Then their is the ultimate terrible reason seller. MY WIFE IS MAKING ME SELL IT! Poor fellow!! Sometimes it's priced way to high so it want sell and then theie is the really low price sale because he knows he has to sell quick or the wife will ..... :shock: :shock:
About 15 years ago I missed buying a 1 year old Jaguar cheap. Doctor's wife put it in the paper for $1,500. We though it was a misprint until we found out she caught him with his girlfriend it the car. Took everything he had; cars, boat and small plane and sold 'em really cheap.
