The BMW 3 SERIES (1998-06) 330D 2DR COUPE CD SE EU4 is a two-door diesel coupe from BMW’s compact executive range, offering a more stylish, driver-focused alternative to a family hatchback or saloon. In UK used-car terms, it sits between mainstream family cars and pricier premium grand tourers, with a smart cabin and room for occasional rear passengers. Mycarcheck.com records 67 look-ups covering 20 different VINs, giving a useful snapshot rather than a huge sample. The average private-sale valuation is £1,300, while the average recorded mileage is 137,000 miles and annual mileage is 5,000. Checks show an average of about five previous keepers. Its six-cylinder diesel character suits commuters and couples wanting comfortable long-distance travel, strong passing power and a more engaging drive than many rivals. It is less practical than a four-door 3 Series, and age means condition matters: check service history, mileage and ownership carefully before buying.
