Maybe putting up for auction could be a good move, only time will tell, though I assume you have a realistic reserve on it?
Good luck with the sale, and let us know how you get on with the 100-4, I had a 3000 mk11 many years ago, and wish I still had it as I now can't afford to buy one at todays prices. [Well I could, but don't want to pay all that money for an old, I mean, classic, car now.]
