The AUDI A6 (2004-09) 4DR SALOON 2.8 FSI QUATTRO S LINE TIP AUTO is a large, premium four-door saloon, aimed at buyers wanting more space and refinement than a mainstream family car. In the UK used market, it sits alongside executive rivals such as the BMW 5 Series and Mercedes-Benz E-Class. Mycarcheck.com records 19 look-ups, covering just two distinct VINs, so these figures offer a small snapshot rather than a reliable guide to every car. Within that sample, average recorded mileage is 111,000, annual use averages 5,000 miles, and the typical private-sale valuation is £2,300. Cars had around six previous keepers on average. Its 2.8-litre petrol engine, quattro four-wheel drive and S line styling bring smooth pace, grip and a sportier look. It suits families and long-distance drivers wanting comfort and space, though running costs exceed smaller saloons. Against executive rivals, it stands out for its refined, roomy cabin and poise.
