The AUDI A6 (2008-11) 5DR AVANT 2.0 TFSI EU5 170 S LINE is a large, premium estate car, combining executive-car comfort with the useful load space of a wagon. In the UK used market, it sits above mainstream family estates, appealing to drivers wanting a refined, practical alternative to an SUV. The Avant body suits family holidays, commuting and everyday errands, while the S line trim gives this A6 a sportier look. Its petrol engine offers a smooth, confident drive, and the cabin is designed for longer journeys. It competes with estate versions of the BMW 5 Series and Mercedes-Benz E-Class, with comfort and understated style among its key attractions.
