The BMW 3 SERIES (1998-06) 320CD 2DR CONVERTIBLE 2.0 M SPORT is a stylish four-seat diesel convertible from the compact executive class. In the UK used-car market, it offers a more premium alternative to mainstream family cars, pairing open-air motoring with everyday practicality and the familiar appeal of BMW’s 3 Series range. Mycarcheck.com records 297 look-ups covering 115 distinct VINs, a useful sample of interest in this older model. Checks show an average private-sale valuation of £1,600 and average recorded mileage of 144,000 miles. Typical annual use is relatively modest at 5,000 miles, while the average keeper count is just over seven, suggesting many cars have changed hands over time. Best for couples seeking a stylish weekend car that can commute, it is less practical for families. M Sport styling and diesel economy distinguish it from Audi A4 and Mercedes CLK rivals, with enjoyable driving and BMW appeal remaining strong draws.
