The AUDI A6 (1997-04) 4DR SALOON 1.9 TDI 115 SE is a four-door premium executive saloon, sitting above mainstream family cars in the UK used-car market. Its understated styling and comfortable cabin make it an alternative to an estate or hatchback, with the 1.9-litre diesel aimed at buyers covering longer journeys. Mycarcheck.com recorded 15 look-ups covering 11 different VINs, a modest sample rather than a complete picture of every A6. Within those checks, average recorded mileage was 191,000 miles, with annual mileage averaging 9,000 and around 2.5 previous keepers. The average private-sale valuation was £400, a notable low figure that reflects the age and high mileage represented; condition, history and local demand can change an individual car’s worth considerably. It suits commuters and small families seeking a comfortable, economical long-distance car, and offers a solid, composed drive; compared with BMW 3 Series or Mercedes C-Class rivals, it prioritises space and relaxed travel.
