I wouldnt buy one off pistonheads or ebay, as mentioned by someone else and already decided by me I would ONLY buy one of a well respected forum member who was looking for a change from their pride and joy. I want one, but there is no rush and not in te position this very second.
To give you an example, this is exactly the sort of thing i would have been after. They only thing I would have dont would have been possibly a vinyl wrap (as it doesnt damage the paint and I can go as cutom as i like, then back to standard if and when i wanted to) and maybe some interior changes (nothing drastic) I also wonder how one of these would look on 20" final edition wheels....? (with it slammed as low as I could get it without compromising the handling, a harsh ride is something I CAN live with though)

Most will have done 100k plus by now. If its been well looked after, im not fazed by mileage providing the engine has been well serviced and well looked after. (trim can always be reconditioned)
