Ok guys thanks for the info you have all given me. Just to update, the car is a 3.5i auto 2009 , space grey with red leather heated sports seats ( couple of bolster scuffs and minor interior leather marks ) , pro hi if and pro Nav, DCT , heated steering wheel , extended stowage , extended lighting, ,exterior Mirror package,PDC. With the 296 19 inch wheels. All the wheels were checked today , one has been repaired ( welded ) the rest are sound , new tyres all around . No adaptive suspension though and not M sport. The engine did not smoke from cold although it did sound a little ticky whilst idling but as I remember these engines can sound that way ? Both rear lights have had water in the bottom white section and it's a bits brown and Mankie if I'm honest in the lights now . The car inside was dry, everywhere I looked for signs of leaking , rear boot seals, battery tray, hydraulic roof motor area, behind the seats and both floor pans .The roof works nice and smoothly as it should but the shelf you have to put down to lower the roof as a plastic bracket broken, but that's and easy fix. There are a few chips in the cars paintwork , but nothing really nasty, and in time I think maybe a front bumper respray would make me happier. For a 2009 car I think it's pretty good and with a little TLC I think this would make a very good example . It's got 65,000 on the clock and BMW service history up to 48 k then it's an independent , who also did the mot in April. The car is at an independent dealer who is offering a years warranty ( probably not worth a great deal ! 1000 quid claim limit, unlimited claims ) ..........so........what should I be paying ?
