The AUDI A6 (1997-04) 4DR SALOON 2.5 TDI 163 SE 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 premium alternatives such as the BMW 5 Series and Mercedes-Benz E-Class, offering a discreet, smart-looking choice for longer journeys. The 2.5-litre diesel and comfortable cabin make this A6 well suited to motorway commuters, business drivers and families needing a roomy boot and rear-seat space. Its SE trim gives it a more welcoming feel, while the strong diesel character is useful for relaxed cruising. Compared with smaller, cheaper family cars, it feels more substantial; compared with its German rivals, condition and service history matter especially on an older example. mycarcheck.com has recorded six checks across four VINs; figures are indicative: recorded mileage averages 214,000, annual use 6,000, and around five previous keepers. Average value is £700.
