Any nice trim or interior parts would be good to snag, probably not worth anything but nearly impossible to find.

I had a 74 Imperial that went the same route a few years ago, clean body with no rust and 58k miles but it had been sitting since '78, the mice ate the wiring and interior from '78-'93 while it was garaged and from '93-05 the sun and location where it was stored destroyed the paint/interior and aluminum trim after it was moved outside.
