The AUDI A4 (2005-08) 4DR SALOON 3.0 TDI TDV QUATTRO 233 S-LINE is a large, premium four-door saloon, aimed at buyers wanting more comfort and refinement than an ordinary family car. In the UK used market, it sits among established executive saloons such as the BMW 3 Series and Mercedes-Benz C-Class, with a sporty S-line look. Mycarcheck.com recorded 148 look-ups across 52 distinct vehicles, offering a useful snapshot rather than a complete picture. The checks show an average private-sale valuation of £1,200, average recorded mileage of 144,000 miles and around four previous keepers. These figures point to an older, high-mileage car where condition and service history deserve close attention. Its strong diesel performance and Quattro all-wheel drive make it appealing for confident motorway journeys and poor-weather grip, while the saloon cabin suits couples, small families and regular commuters. Compared with rivals, this A4 stands out for assured traction and discreet, sporty character.
