Sorry to hear you are passing it along but it sounds like you have done some good work with it. Quite the story with the car's history and fame on the internet.
This sounds like a good deal for the right person looking for a project. If it's a complete set of diesel special tools with the car, those are worth your asking price alone, especially if you have some greenbooks and spares going with it too. Do you have any pictures of the additional stuff that is included? That will probably help your sale.
One tip: definitely don't want to run it on starting fluid -- even if it's just for a second, to prove to a potential buyer that the engine runs, etc. It can be very tempting to give it a whiff for various reasons, but it is best to resist.
Hope it goes to someone who will keep it rolling and continue to participate on the forum. Good luck with the sale.
