The AUDI A6 (1997-04) 4DR SALOON 1.9 TDI 110 is a large, four-door family and executive saloon, sitting in the UK’s traditional premium-car class alongside the BMW 5 Series and Mercedes-Benz E-Class. Its understated styling and spacious cabin make it a more grown-up choice than a compact hatchback, while the diesel engine suits longer journeys. mycarcheck.com has recorded seven checks across seven distinct VINs for this exact A6 variant, a small sample rather than a broad market picture. Those checks show an average private-sale valuation of £500 and average recorded mileage of 239,000 miles; annual mileage averaged 13,000, with nearly five previous keepers on average. These figures suggest high-mileage, well-used examples, so condition and service history deserve close attention. It suits commuters and small families seeking a comfortable, fuel-conscious long-distance car. Against newer rivals, it offers a substantial, refined feel for little money, but age makes careful checks essential before purchase.
