There's no getting around it. For any proper coupe restoration, the fenders HAVE to come off. That's a known weakness and if if you are going to spend 100k, ALL the rust has to be discovered and that means everything....Question is, does that car need to have the fenders taken off? I can’t really tell from the video, but it looks pretty good and he didn’t mention any rust other than the floor pan. Maybe have it “scoped” to see if there is rot behind the front fenders and if not play the lotto and keep the job simpler and the costs down.
