The car sat outside for a number of years prior to my purchasing it and developed rust holes and leaks in the roof, destroying the seats and carpet of the interior. In the left picture you can see mildew-infested carpet and seats. The picture on the right shows a surface rust that was underneath the rear seat.
The floor under the front seat and carpet was in much better shape than under the back seat. There was hardly any rust in the front floor pans at all.
