The AUDI A6 (2004-09) 5DR AVANT 2.7 TDI 180 LE MANS is a large, premium estate, with useful luggage space and a smart, executive-car feel. In the UK used-car market, it sits among spacious family and business cars, competing with estate versions of the BMW 5 Series and Mercedes-Benz E-Class models. Mycarcheck.com records 196 checks covering 82 different cars, giving a snapshot rather than a complete picture of every example. The average recorded private-sale value is £1,400, with mileage averaging 177,000 and about four previous keepers. Average annual mileage is 7,000, so condition, service history and individual vehicle checks matter greatly. Families, commuters and holiday-makers will value its spacious load area, relaxed motorway ride and comfortable cabin. Le Mans styling and equipment give this premium diesel estate extra appeal against BMW and Mercedes rivals, while its strong long-distance character suits regular travel. At this age, check condition and service history carefully.
