Maybe cause you seem so desperate to sell it?
Judging by the forum there aren't that many people on the lookout for one at the moment, everyone that wants one seems to have one and anyone who is still looking for one is looking for one in a newer condition than many daily driven UK based ones are in.
You bought it at the time there were a few buyers on the lookout for one, and are selling it at a time that they've all found their teggy. Patience required, otherwise if you are that desperate drop the price and eventually someone will take a punt on it cause its got stupidly cheap.
Also with these cars you are buying them based on the previous owner IMO, and judging by the impression you've given out so far from your time here you seem....... rather......."intense" probably the best way of putting it, which would put me off if I'm being honest. This is the 3rd thread you've made about selling it that I can recall off the top of my head being the case in point. So chill out and eventually it will sell.
