The AUDI A6 (2008-11) 5DR AVANT 2.0 TDIE CR DPF EU5 136 S LINE is a large, premium five-door estate, aimed at buyers wanting executive-car comfort with useful carrying space. In the UK used-car market it sits above mainstream family estates, competing with the BMW 5 Series Touring and Mercedes-Benz E-Class Estate. The 2.0-litre diesel S line combines a composed, comfortable feel with a smart, sporty look, while the estate layout suits school runs, commuting, holidays and everyday loads. It is best for families or regular long-distance drivers who want more refinement and room than a hatchback, rather than a small, inexpensive city car. mycarcheck.com records 306 checks across 134 VINs: an average private-sale value of £3,000, mileage of 157,000 miles, annual use of 8,000 miles and about three previous keepers.
