The AUDI A6 (1997-04) 4DR SALOON 2.5 TDI 155 SE MTRON AUTO is a large, four-door executive saloon: a traditional alternative to an SUV or family hatchback, aimed at buyers wanting space and comfort. In the UK, it sat alongside the BMW 5 Series and Mercedes-Benz E-Class, offering a restrained, upmarket feel. mycarcheck.com has recorded seven look-ups across six distinct VINs, so this is a modest sample rather than a complete picture of every car. Within those checks, the average private-sale valuation was £1,100, average recorded mileage 133,000 miles, and annual mileage 10,000 miles. Cars had an average of just over five previous keepers, making condition and service history especially important when viewing one. Its diesel and automatic suit motorway commuters, while the roomy cabin and boot work for families. Comfortable and understated, this Audi A6 saloon rivals BMW and Mercedes executive cars, but age makes checks vital before buying.
