The forum is free advertising (once you have enough posts), so given an ED30 is maybe a bit niche to anyone not really a VW follower, you could do worse than a for sale post on here with lots of info and detailed pics of the condition of your car.
Whilst the ED30's are now getting on in miles, and I do see a few low milers out there - I note very few one owner examples. That is one great selling point you have right there to someone on the enthusiast forums!
I know some will scoff and say what does it matter, but whilst mine has full VW history in the book from the 3 owners (47k) before me, I don't have all of the invoices to back it up. It was an 'approved used VW' (make of that what you will). I reckon I can get some history reprinted via my dealers if I am nice (they've previously told me what warranty work my car has had - air-con pump, thank god ...££££) but still I'd love the entire history of my car.
Yours should appeal as a very genuine example if you have all the history. Someone will travel for it.
