I ran across a green GMC jimmy today, I was in a rush and didn’t take any pictures but I did chat up the owner and he said it’s a 1975 and he wants $1,000. I didn’t see any visible rust but it’s been sitting for a while, it’s got the full convertible hard top, missing front windshield and hood and dash pad, interior is trashed and I’m worried about rust in the pan since it’s got a lot of debris in there from sitting under a tree. If anyone were seriously interested I can go back and get better info and give it a better look. The rear tailgate has a small tear in the upper left corner and what looked to be factory green paint is in good shape and the rear window is either down or missing as well also missing factory wheels.
I didn’t try lowering the tailgate.
