When i advertised my 25th Anniversary in July prices were all over the place, ranging from £4.5k upto £8995. I tried my luck at £7495, but soon lowered it with only one interested party at Inters. Mine was a genune mint example, FVWSH and 72k on the clock. Sold after 5 weeks for £6500, for a nearly 9 year old car, i was pretty happy in the end.
When looking at ED30's you could find a car at £10-11k, but if it didnt have xenons, MFSW, armrest, highline etc.. you could well end up paying out a further £1k to retro-fit. Im very happy with the car i have just bought, silver dsg 5dr, 1 owner from new, FVWSH, xenons, highline, armrest, usb and 42k on the clock. Paid that little more as i found it at a main dealer, so happy to take the warranty to cover the DSG box and have come back with any issues i may have.
All the best with finding the right one, but you have to be willing to travel. I travelled upto scotland, to Norwich, to South Birmingham, from west yorkshire, to find sheds, only to find one 26 miles away on barnsley
