The AUDI A6 (1997-04) 5DR AVANT 2.4 V6 170 QUATTRO SPORT is a premium five-door estate, offering executive-car comfort and family-friendly load space. In the UK used-car market, it is now an older, affordable alternative to newer estates, with Quattro four-wheel drive adding reassurance in poor weather. mycarcheck.com records one check for this exact version, covering one VIN, so its figures are only a small snapshot. The record gives an average private-sale value of £800, mileage of 183,000, annual use of 7,000 miles and four previous keepers. Check condition, service history and paperwork, as individual cars can vary. The Avant suits families needing practicality, while its V6 delivers smooth, relaxed performance. Quattro grip and Sport trim give Audi a distinctive character, setting it apart from estates, and it competes with BMW 5 Series Touring and Mercedes-Benz E-Class estates. Expect fuel and upkeep costs to exceed those of a smaller, newer car.
