There is a house near where my brother lives. In the drive way sat a 78 Z28, 70 SS 396 Chevelle, 70 RS Z/28 and a 71 SS Chevelle convertible. I watched them all rust away. Once I was chased a way but most other times no one answered the door. Cars a gone now. Probably sunk right thru to the ground.
Rick you know about this one.
Found another house that has what looks to be 2 67-68 Firebirds under tarps and a 64 or 65 Comet rolling chassis.
Years ago on a vacation I found a 69 SS 350 pace car in back of a restaurant. Just sitting there among some other older cars. Owner wasn't budging at the time. Follow up phone calls didn't work either.
After taking my son for a walk a few years ago my wife told me she thought there was a Camaro in a garage 2 blocks away. Sure enough I found that this person bought his brothers 69 RS Z/28 Olympic Gold. Currently he is restoring the car. Should be done soon.
