BMW 6 Series used-car buying guide: should you buy one?
The BMW 6 Series is a premium grand tourer family covering coupe, convertible, Gran Coupe and Gran Turismo body styles. Buyer risk depends on exact generation, engine, roof type, diesel emissions equipment, automatic gearbox, suspension, tyres, brakes, electronics and service evidence.
Strong long-distance comfort and premium image, but expensive-car running costs remain even when used prices look attractive.
