The AUDI A4 (2001-05) 2DR CONVERTIBLE 2.5 TDI is a four-seat, open-top version of Audi’s compact executive car, sitting above ordinary family convertibles in the UK used market. Its folding roof gives it relaxed summer appeal, while the diesel engine makes it more suited to longer journeys than short town trips. It is a stylish alternative to a conventional saloon, though rear-seat access and boot space are less convenient. mycarcheck.com recorded 22 look-ups covering 18 different cars, so these figures offer a small snapshot rather than a market-wide picture. Checks show an average private-sale value of £600 and average recorded mileage of 133,000 miles. Typical annual use was 6,000 miles, with about four to five previous keepers. Mileage points to moderate use; check each car’s history. Against BMW 3 Series and Saab cabriolets, the A4 offers understated comfort and long-distance diesel appeal, rather than buyers needing extra space or low costs.
