The AUDI A6 (2004-09) 4DR SALOON 2.8 FSI SE MTRON AUTO is a large, four-door executive saloon, aimed at buyers wanting more space and comfort than a family hatchback. In the UK used-car market it sits alongside the BMW 5 Series and Mercedes-Benz E-Class, offering a refined, understated alternative. Its 2.8-litre petrol engine and automatic gearbox make it well suited to relaxed commuting, motorway journeys and comfortable family travel, rather than low-cost town driving. The SE version brings a well-appointed feel, while the A6’s spacious cabin, composed ride and quiet manner are notable strengths; buyers should allow for higher fuel costs than with smaller cars. Mycarcheck.com recorded 10 look-ups covering five distinct cars, so figures are indicative rather than a market survey: average private-sale value was £1,400, mileage 106,000 and annual use 6,000 miles, with about four previous keepers. This used Audi A6 suits comfort-focused buyers who value refinement over economy.
