The AUDI A6 (1997-04) 4DR SALOON 2.5 TDI 163 MTRON AUTO is a large, four-door executive saloon: a comfortable, diesel-powered alternative to mainstream family cars. In the UK used-car market, it sits alongside models such as the BMW 5 Series and Mercedes-Benz E-Class, offering a more understated approach to premium motoring. Its spacious cabin and automatic driving suit commutes, motorway journeys and family travel. The 2.5-litre diesel is aimed at economical miles, while the saloon offers a separate boot and refined feel. Against sportier rivals, comfort and quiet cruising define its appeal. Mycarcheck.com has only two look-ups for this exact version, covering two VINs, so the figures are a small snapshot rather than a firm guide to every car. Those records show an average recorded mileage of 165,000, around 5,000 miles a year, 6.5 previous keepers and an average private-sale valuation of £300. Check each individual car’s history and condition carefully.
