A friend of mine in Europe sold one (of the expensive ones) last year for I believe he said around $280,000, I think he was the first owner. I could not believe the price but, that said, I recall when I was living in Florida in the eighties nice ones were already then valued around $100,000 - sort of a status symbol back then, similar to the G-wagen today.
Funny, my price range for what I consider an 'affordable restoration project' tops out at $7,500!
