The BMW 3 SERIES (1998-06) 330CD 2DR CONVERTIBLE 3.0 SE is a two-door, four-seat premium convertible, offering an open-air alternative to the executive saloon rather than the practicality of a hatchback or SUV. Its diesel power and relaxed character suit longer journeys, while its classic BMW styling still feels special. Mycarcheck.com has recorded 27 look-ups covering 12 distinct VINs, so this is a useful snapshot rather than a large survey. Across those checks, the average private-sale estimate was £1,500, recorded mileage averaged 154,000 miles, and annual mileage was about 5,000. Cars had an average of 4.3 previous keepers, worth checking against each car’s history. Best for couples or solo drivers wanting a weekend car that can commute comfortably, it offers refinement and engaging 3 Series character. Its diesel may use less fuel than petrol rivals, but check service history, roof operation and condition carefully before buying, given its age and mileage.
