The AUDI A4 (2001-05) 4DR SALOON 3.0 QUATTRO SE 6SPD is a premium, four-door family saloon from the early-2000s, aimed at buyers wanting comfort and refinement rather than a small, inexpensive runabout. In the UK used-car market, it sits among established executive saloons, competing with alternatives such as the BMW 3 Series and Mercedes-Benz C-Class. mycarcheck.com has recorded 25 checks covering eight distinct VINs, a modest sample, offering a snapshot rather than a complete market picture. Those records show an average private-sale valuation of £500, average recorded mileage of 124,000 miles, and 2,000 miles driven annually. The average number of previous keepers is nearly six. The 3.0-litre petrol engine, six-speed manual and quattro four-wheel drive bring grip and relaxed long-distance comfort, though fuel costs may be higher than smaller rivals. This A4 suits experienced drivers wanting an engaging commute or family saloon; check its condition and service history before buying.
