The AUDI A6 (2008-11) 5DR AVANT 2.7 TDI CR DPF EU5 190 S LINE MTRON AUTO is a large, premium five-door estate, offering more luggage room than the A6 saloon while retaining executive-car comfort. In the UK used market, it suits buyers today wanting a spacious alternative to an SUV, with smart S line styling and an automatic gearbox. mycarcheck.com records show 26 look-ups covering seven distinct VINs, a useful but modest snapshot rather than a full picture of every car. Across those checks, the average private-sale valuation was £3,700, recorded mileage averaged 141,000 miles, and annual mileage averaged 7,000. The cars had about 3.3 previous keepers on average, so check each vehicle’s history and condition carefully. Its 2.7-litre diesel and relaxed automatic suit family trips and motorway commuting; S line trim adds a sportier look. Against BMW 5 Series and Mercedes E-Class estates, it offers a similarly upmarket, practical feel.
