Needs to be the 8-speed auto, not the previous 6-speed. Makes a big difference. High mileage clocked up quickly is good for a car as long as it has been properly maintained, so check its service history. 10k mile oil changes very good. 20k oil changes very bad. If okay, work on the price by pitching a counter offer of, say, £25k, bearing in mind that the car originally cost £60k plus, and negotiate from there.
