I though "oh god what was he thinking" when I saw the first pictures, but looking closer that looks an ideal project for someone who's got a dry garage and time. It's an ideal one to pick away at a bit at a time. Assuming it's not utterly rotten underneath though, given there are obvious signs of water ingress...does it actually still have floorplans?
Echoes of the T25 camper I had...it looked like it had been dredged off the bottom of the North sea, yet I only managed to poke holes in a single chassis outrigger, and despite having sat for eight years it started, drove and stopped just fine. Thing even braked in a straight line...sadly then my father moved house so I had to pass it on in a hurry. It was definitely doable, but needed a lot of time spent on it.
Dunno...maybe I'm just a real sucker for the whole giving a car a second chance thing...have only scrapped a couple and it still troubles my conscience.
Silver Spirit is definitely on my future shopping list (hopefully not too distant given the way prices are going), but given that I'm an abject coward, it will probably be an expensive one from a specialist with documented evidence of all of the cripplingly expensive jobs having been already done. There's something that just appeals to me about baffling my neighbours by parking a Rolls next to the Lada on the driveway...because it sure as heck won't fit in the garage.
That's assuming I don't wind up buying a 70s era coach instead mind you...funny that they suffer from a strangely similar list of potentially exciting ways to bankrupt you if you're not careful.
About as difficult to park as each other too...
