The AUDI A6 (2008-11) 4DR SALOON 3.0 TDI CR DPF EU5 240 QUATTRO S LINE SPECIAL EDITION 6SPD is a large, premium four-door saloon, aimed at buyers wanting executive-car comfort rather than a small family hatchback. In the UK used market, it offers an upmarket alternative to the BMW 5 Series and Mercedes-Benz E-Class. Mycarcheck.com recorded 20 checks covering 11 different VINs, giving a useful snapshot rather than a huge sample. Checks show an average private-sale valuation of £4,900 and average recorded mileage of 123,000 miles. Cars averaged 7,000 miles a year and 2.45 previous keepers, details worth weighing alongside condition and service history. This A6 suits commuters and families seeking a comfortable long-distance car with room for passengers and luggage. The 240-horsepower diesel and Quattro four-wheel drive bring assured progress, while S line trim adds a sportier look. It feels substantial than mainstream saloons, but check running costs before buying.
