The AUDI A6 (2008-11) 4DR SALOON 2.0 TFSI EU5 170 S LINE is a spacious premium executive saloon, sitting above mainstream family cars in the UK used-car market. Its four-door layout and comfortable cabin make it a sensible alternative to an SUV for drivers wanting refinement, room and a more traditional, composed road presence. Mycarcheck.com has recorded 22 look-ups across eight distinct VINs, so the figures offer a useful snapshot rather than a large-scale verdict. The average private-sale valuation is £4,100, with average recorded mileage of 108,000 miles and annual use of 5,000 miles. Checks show about three previous keepers on average, useful context when assessing a car’s history. The 2.0-litre petrol engine and S line styling give this A6 a smart feel, while its roomy cabin suits commuting, business travel and families. It rivals the BMW 5 Series and Mercedes-Benz E-Class with understated comfort; check service records and condition carefully.
