The AUDI A4 (2001-05) 4DR SALOON 3.0 QUATTRO SE is a compact executive four-door saloon, sitting above everyday family cars in the UK used-car market. It blends a smart, understated cabin with a powerful petrol engine and Audi’s four-wheel-drive system, making it a more performance-minded choice than a basic family saloon. Its discreet styling still feels purposeful rather than flashy. mycarcheck.com has logged eight checks for this model, covering just two distinct VINs, so the figures are a small snapshot rather than a reliable market-wide guide. Within that sample, average recorded mileage is 144,000, average annual mileage 2,000, and the average keeper count is nine. The average private-sale valuation is £300; treat this cautiously, as individual condition, history and running costs can greatly affect price. It suits commuters or small families seeking secure all-weather comfort, but expect higher fuel and upkeep costs than mainstream rivals. Its quattro traction stands out.
