The AUDI A6 (1997-04) 4DR SALOON 1.9 TDI 130 SPORT MTRON AUTO is a large, four-door executive saloon aimed at buyers wanting more space and comfort than a family hatchback. In the UK used-car market it sits among older premium cars, offering a more upmarket feel without today’s premium-car purchase price. It is well suited to commuters and families needing a roomy cabin and boot, with diesel economy appealing on longer journeys. mycarcheck.com recorded 17 look-ups across 11 distinct VINs, a modest sample, not a full market picture; records show average mileage of 143,000 miles and annual use of 8,000 miles. The Sport trim adds a purposeful character, while the automatic gearbox makes relaxed driving easy; its blend of comfort and diesel economy helped it rival the BMW 5 Series and Mercedes-Benz E-Class. Check history: sampled cars averaged about £1,100 and nearly six previous keepers, so condition matters more than appeal.
