Cool cars you found but owner wouldn't sell !
Not a Mopar, (sorry) but there was a 1968 Firebird sitting in a field behind a guy's house. Knocked on his door, said it is a former drag car, interior is stripped, not for sale. Six months later, the car is gone. Not sure what happened to it.
Also not a Mopar, (sorry again!), when I was stationed at Alameda NAS in California back in the 90s, I drove a buddy to his parents house in Gridley, CA, and his dad had an old BMW (late 60s, early 70s) sitting in the bushes. Told me if I could get it running and get it off the property, I could have it. Kicking myself now for not trying, at least. Oh, well. Live and learn.
