The AUDI A6 (2008-11) 4DR SALOON 3.0 TDI QUATTRO S LINE TIP AUTO is a large, premium saloon for drivers who value comfort, space and composed long-distance travel. In the UK it competes with the BMW 5 Series and Mercedes-Benz E-Class. Its S line trim adds a sportier look, while the automatic transmission and four-wheel drive make it an appealing choice for year-round journeys. It suits business users, couples and families needing a roomy cabin and generous boot, and is particularly at home on motorway commutes and longer trips.
