Ed's are a funny beast to sell at the mo. i recently sold mine (and struggled to sell it I might add) Mint with low miles, and I say it was mint, others reckon it was better than new. 20K miles. Spec was poverty spec, Cruise, and Armrest were the only options. Had 4 fairly new PS2's, FSH, even had unused Red trimmed Genuine mats.
Still struggled to get an acceptable price.
I do think there is a romantic notion that Ed's are worth that much more over a standard Gti. I sadly think that this is not borne out given the market reluctance to buy.
I had 4 viewings, 3 wasters who wanted it for nothing, and the final guy was a genuine buyer, who knew what he was looking at and the condition of the car.
Sorry if that bursts the bubble, but just my recent experiences, which are borne out by the number on prolonged sales in the Trader, on PH and even on this site.
