The AUDI A6 (1997-04) 4DR SALOON 2.5 TDI 163 SE MTRON AUTO is a roomy, four-door executive saloon, aimed at buyers wanting comfort and long-distance ability rather than a small town car. In the UK used market, it sits alongside the BMW 5 Series and Mercedes-Benz E-Class as a family and business car. The 2.5-litre diesel and automatic gearbox suit motorway commuting and journeys, while the roomy cabin and boot make this A6 useful for family travel. Its appeal is relaxed cruising, a comfortable ride and an understated feel; it is less at home as an economical choice for short urban trips.
