The AUDI A6 (1997-04) 5DR AVANT 2.0 SE MTRON AUTO is a large, five-door estate: a practical, upmarket alternative to a family hatchback, aimed at buyers needing more room and comfort. In the UK used-car market it sits among executive estates, competing with versions of the BMW 5 Series Touring and Mercedes-Benz E-Class Estate. Mycarcheck.com has recorded four checks, covering four different cars, so these figures offer a small snapshot rather than a reliable market average. Those cars averaged £900 in private-sale value and 137,000 miles, with about 9,000 miles added yearly and 3.25 previous keepers. Treat each figure as a guide, not a guarantee. The Avant shape brings useful luggage room for family trips, shopping or hobbies, and the automatic suits relaxed commuting. SE trim gives a comfortable, well-equipped feel. It suits buyers seeking spacious executive-car comfort at modest cost, provided its condition and maintenance history check out carefully before purchase.
