I know this car has sat inside for the at least the last 30 yrs right next door . The rust was there when I first bought it. It was a Jersey shore car. Probably sat right on the beach when the original owner bought it. The first pictures I was the second owner the rust was there in the early 80's. It is a shame this car was still a very stout fast car up until about a month ago when I stole the brakes. It was fun to take out and put an *** whooping on it.
