I have my own story to tell about this clown too.  I live about an hour-and-a-half from Rockford, and in my Friday newspaper one week was a classified ad for a 1980 Cadillac flower car.  I recognized the area code as being somewhat local, and since I have a 1980 hearse, I called on it.  
I was told "just out of service, runs great, no rust".  I said I'd come by tomorrow to see it, and got directions to his "dealership".  Well I drove past the place twice trying to find it, looking for his nonexistant dealership, before I turned in at the mailbox with the right address number on it.  What he called a dealership, I would call a junkyard.  It was a bunch of rusted hulks in a field, some complete with trees growing where the engines should be.  
Finally I was lead to the flower car.  Maybe it was just out of service, I don't know.  Maybe it did run great, I didn't try to actually drive it.  I didn't see any obvious rust.  Bu what he didn't tell me was that it looked like it had been in a demo derby.  There literally was not an undamaged panel on the whole car.  Maybe the service it was just out of was someone's using it as a pickup truck beater.
Nonetheless, I figured it didn't hurt to ask the price, thinking it was worth maybe $500-$1000.  I darn near fell over in the mud when he said it was $8500, and proceeded to tell me how rare and valuable it is.  Out of curiosity, I also asked about a couple of the other cars I had seen sinking into the mud.  They were all $7000-$12,000, because, as I was told, they are all antiques.
Needless to say, I left, realizing what a crook this guy is.  But there is a postscript to this story...
Literally years later, I was at a car show, and an 80s Cadillac flower car pulled in with dealer license plates on it, so I go over to check it out.  Guess what, its the same car, still trying to be sold by the same guy, now it is rusting, and its still $8500.
Go figure.
