Yeah, keeping an eye on Autotrader and Piston Heads, really looking for space grey with beige leather, might consider dark blue.
I'd rather wait for a good one in my choice of colour, seen some real rubbish up to now though
The best one so far was a guy in Oxford, pretty basic spec SE with limited pics on Autotrader. I asked for more pics and one from the front shows a very nasty dent where the grills have been pushed into the bonnet (not mentioned in ad), the guys description was 'excellent condition'....LOL. The joker even wants proper money for it considering it's a private sale with no warranty.
The thing is that all I have seen so far haven't been looked after, with all the different cars i've purchased over the years I think that finding a genuine X5 4.8 is going to be tougher, maybe I won't find one and will move on.
