The AUDI A6 (2008-11) 5DR AVANT 3.0 TFSI EU5 290 QUATTRO S LINE TIP AUTO is a premium five-door estate, combining useful luggage space with executive-car comfort. In the UK used market, it sits above mainstream family estates, appealing to buyers seeking comfort, pace and all-weather confidence for everyday family use. Mycarcheck.com records 150 look-ups covering 43 distinct VINs, a useful sample for this version. Checks show an average private-sale valuation of £4,100 and average recorded mileage of 103,000 miles; typical annual use is 6,000 miles, with around 3.4 previous keepers. These figures offer context, not a price or condition guarantee. Families and commuters value its roomy cabin and estate boot for trips and weekends away. The petrol engine, automatic gearbox and four-wheel drive give this S line a brisk, reassuring feel and sporty style. Against BMW and Mercedes estates, it is a distinctive, capable alternative, though running costs need budgeting.
