The AUDI A6 (2008-11) 4DR SALOON 2.0 TDI CR DPF EU5 170 S LINE SPECIAL EDITION 6SPD is a spacious, premium family saloon, sitting above mainstream family cars and competing with models such as the BMW 5 Series and Mercedes-Benz E-Class. Its smart, understated styling suits business and everyday use alike. The 2.0-litre diesel offers relaxed long-distance cruising and useful fuel economy, while the S line Special Edition brings a sportier look and a well-equipped feel. It is best suited to commuters, company-car drivers and families wanting a comfortable, roomy car for motorway journeys; its larger size makes it less convenient in tight city streets than a hatchback. Mycarcheck.com records 1,021 checks across 447 distinct VINs, a substantial sample; the average private-sale valuation is £3,900. Recorded cars average 128,000 miles, around 9,000 miles a year, and nearly four previous keepers. These are useful guideposts, not a guarantee for any individual used A6.
