not autotrader, they ran my ad three times and I only appeared to get enquiries that strangely came to nothing a couple of days before the ad renewal date, still could just be coincidence?
What seem's to now be working for me is, not try and sell it, but rather drive it around (no sign advertising it for sale) and then get asked by people "is it for sale?" or "would you consider swapping it for this + cash?".
I didn't try ebay but tried everywhere else, I think if I do come to sell it (which I no longer have any plans to do) then I'll chuck it on ebay and let it run an go for what it goes.
