The AUDI A6 (2008-11) 5DR AVANT 2.7 TDI CR DPF EU5 190 QUATTRO SE TIP AUTO is a premium executive estate, with generous space for passengers and luggage alike. In the UK used-car market, it rivals estate versions of the BMW 5 Series and Mercedes-Benz E-Class, offering a practical saloon alternative. Mycarcheck.com records 41 look-ups covering 19 distinct cars, a useful snapshot rather than a huge sample. Checks show an average private-sale value of £2,700, average recorded mileage of 174,000 miles and annual use of 8,000 miles. Cars had about three to four previous keepers on average, so condition and history deserve close attention. The 2.7-litre diesel and automatic suit motorway commuting, long trips and family holidays; quattro four-wheel drive adds reassuring grip. The Avant’s roomy cabin, refined ride and strong pulling power make it a comfortable alternative to rival German estates, though age, mileage and upkeep matter at this price.
