The AUDI A6 (1997-04) 4DR SALOON 1.9 TDI 115 is a large, four-door executive saloon, sitting above compact family cars in the UK used-car market. It offers a roomy, comfortable alternative to a hatchback, with a traditional boot and a more formal feel, appealing to buyers who value space and long-distance comfort. mycarcheck.com has recorded just one check and one distinct VIN for this exact version, so its figures are a small snapshot rather than a reliable market average. That record shows an average private-sale valuation of £400, 200,000 miles, 7,000 miles a year and three previous keepers. These details suggest a high-mileage older car, so condition and service history matter greatly. Its diesel engine and relaxed character suit commuters, motorway drivers or families wanting a spacious saloon. Against BMW 5 Series and Mercedes-Benz E-Class rivals, the A6 is known for understated comfort and premium appeal; check any example carefully.
