Cool cars you found but owner wouldn't sell !

I have found many. All my life my Dad, uncle, and brother have always been on the car lookout. The nervouse exciting knock on the door do you want to sell that car ? Not for sale im gonna fixx it someday, come back later, or get out of here you are on private property, or for the right price , or get it out of here !! The saddest are it's not for sale and you watch it deteriorate over the years, or you come back time n time again until one day it's gone !
One car that pops out when I think of tis is a 1971 challenger R/T 340 4speed curios yellow I found it in 1988 watched talked to the guy he was not nice acted paranoid, I went back severl times then in 2005 it was gone. Not sure what happened to it ?
I have many other stories similar that one just pops out !! What are your stories ?:happy1:
