The AUDI A6 (2008-11) 4DR SALOON 2.7 TDI CR DPF EU5 190 S LINE is a large, premium four-door diesel saloon, aimed at buyers wanting more space and refinement than a family hatchback. In the UK used-car market, it sits among executive cars such as the BMW 5 Series and Mercedes-Benz E-Class, offering a smart, understated alternative. Mycarcheck.com records 21 look-ups covering eight distinct VINs, so the figures offer a useful snapshot rather than a broad market survey. The average private-sale valuation was £3,400, while recorded cars averaged 151,000 miles, around 7,000 miles a year, and three previous keepers. Well suited to commuters and families, it offers a comfortable motorway drive, roomy cabin and useful boot. S line trim adds a sportier look, while the 2.7-litre diesel is relaxed on long trips. Against rivals, it combines understated style with premium feel; check service history and condition carefully on any older example.
