The AUDI A6 (2004-09) 5DR AVANT 2.0 TDI TDV SE MTRON AUTO is a large, premium estate car, rather than a hatchback or SUV. In the UK used-car market, it offers Audi’s executive-car feel with the extra boot space and practicality buyers often want from a family estate. On mycarcheck.com, this model has attracted 692 look-ups covering 276 different VINs, a substantial sample that suggests continuing interest in older A6 Avants. Checks show an average private-sale valuation of £1,200 and average recorded mileage of 157,000 miles; typical annual use is 12,000 miles, with nearly six previous keepers on average. The 2.0-litre diesel and automatic make it relaxed for commutes and family journeys, while the Avant suits holidays, pets and shopping. It is best for buyers wanting space and comfort, as an understated alternative to BMW 5 Series Touring or Mercedes-Benz E-Class estates. At this age, check service history and condition carefully.
