Well, I just sold a pretty mint 54 plate in Aberdeen (grey, plenty extras including Monzas), FVWSH, 45k, got a shade under 9.5k for it. Not a great price, but there seemed to be plenty 05s on Autotrader/Pistonheads for under 9k so had to be competitive. Didn't get much interest when it was over 10k and had to get it shifted as had bought another car.
Kind of wish I'd held off another couple of weeks though as the forum seems to be full of folk looking for cars now!
Best to avoid dealers, I'd try auction, should be able to pick up one up there for a good price. Try signing up for
www.auctionview.co.uk so that you can find suitable cars. Just cut out the middleman!
