The AUDI A6 (2004-09) 4DR SALOON 2.8 FSI SE is a four-door executive saloon, aimed at buyers wanting more comfort and refinement than a mainstream family car. In the UK used market, it sits alongside alternatives such as the BMW 5 Series and Mercedes-Benz E-Class, offering a polished, understated choice for longer journeys and everyday driving. Its 2.8-litre petrol engine gives the A6 a smooth, relaxed character, while the SE trim focuses on comfortable, well-equipped travel rather than sporty looks. The spacious cabin and boot make this Audi suitable for couples or families, business users and commuters who regularly cover motorway distances. Compared with smaller saloons, it feels more substantial and quiet, though fuel costs are likely higher than in modest-engined rivals.
