The pop riveted on SS covers are probably just cosmetic but I agree that you will miss the foot room with the flat floors he has put in. That would not be a deal killer for me provided other areas are good and the price is right. Its not uncommon for someone to not keep the rain out and a fairly solid car can have bad floors. Rut covers the really important parts though. From what little I see of the rear spring mount it could be fairly solid.
