The AUDI A6 (1997-04) 4DR SALOON 2.0 SPORT is a large, four-door executive saloon, sitting above everyday family cars in the UK used-car market. Its understated styling and roomy cabin suit drivers wanting a comfortable, more substantial alternative to a mainstream hatchback, without moving into SUV territory or buying a new car. Mycarcheck.com recorded 40 look-ups for this version, covering three distinct VINs, so the figures offer a small snapshot rather than a market-wide verdict. Checks show an average private-sale value of £500, average recorded mileage of 121,000 and annual mileage of 6,000; cars averaged about nine previous keepers in the data. That pattern suggests an older used car, best considered by budget-conscious commuters or families who value comfort and a generous boot, rather than low running costs or modern technology. Against BMW 5 Series and Mercedes E-Class rivals, the A6 is known for composed ride and understated quality; inspect history carefully.
