The AUDI A6 (2008-11) 4DR SALOON 2.7 V6 TDI DPF EU5 190 QUATTRO S LINE SPECIAL EDITION TIP AUTO6 is a large, premium four-door saloon, sitting alongside executive cars such as the BMW 5 Series and Mercedes-Benz E-Class in the UK used market. Its S line styling gives it a sportier look, while quattro all-wheel drive and an automatic gearbox make it appealing for confident, comfortable year-round travel. Across 74 mycarcheck.com look-ups covering 32 different VINs, the average private-sale valuation was £4,800. The cars checked averaged 114,000 miles, around 9,000 miles a year, and nearly five previous keepers, useful context when judging any individual example. This is a substantial, well-equipped diesel saloon rather than a small city car: it suits longer commutes, business travel and families wanting generous cabin space and a composed motorway ride. Its V6 engine offers smooth, relaxed performance, while diesel economy can help on longer journeys; age, maintenance and emissions-system condition matter, so check records and history carefully before buying any example.
