By the looks of that interior, it may have been a rather low mileage car put away and forgotten. Someone probably drug it out of a garage or barn and started working on it, primed it at let it sit and rot again
This looks like it might be a fairly easy resto; - that is until you get it into the air and see if there's anything left underneath. It's worth a shot...
