Here is my 1983 buick riviera 20th anniversary car (project). Interior floors are mostly solid with a few minor areas to repair, literally half the trunk floor is rotted out and just air and the panel the tailights go into is half rotted out. Needs everything. But its coming. What buick used as a "frame" is solid and the rockers are solid. Need to locate hubcaps, trim rings, and 2 wire wheels since 2 of the wheels are bad. Also need a good passenger side door and other stuff, its a slow process.
