LOL my point was its a lot of grief compared to selling it normally, and there are a lot of hidden costs, not to mention the possibilty of a complete litigious idiot winning it and making your life a total drag afterwards!
The V12 dax for sale for over 2 years is either a pup, poorly advertsied or overpriced; anything will sell if its well presented around market value, and Ive seen a few Dax V12's sell for 12-14k, and my guess is your costs I mentioned above would be close on £1000 ish all told, not counting all the time it would take?
Far easier and quicker to just drop the price a bit if it doesnt sell at your asking price; Ive always been a fan of piston heads, as Dave says its free so no risk at all (bar a few emails from dreamers who dont turn up at the appointed time

; its worked for me twice selling cobras, one for £20k one for £24k but you do have to put up with a few idiots, put loads of details and good pics up, and revise the advert comprehensively at least every couple of weeks to keep it high in the ranking.
Good luck with whatever you decide; I have a hunch you dont want to sell it at all; just got the winter blues like me!!!
