The BMW 3 SERIES CONVERTIBLE (2007-14) 330D 2DR CONVERTIBLE 3.0D DPF 245 EU5 SPORT PLUS EDITION STEP AUTO6 is a premium, open-top car rather than a practical family hatchback. In the UK used market, it sits among executive convertibles, combining BMW’s 3 Series shape with a six-cylinder diesel and automatic gearbox. Checks on mycarcheck.com recorded 153 look-ups covering 70 distinct VINs. The average private-sale valuation is £7,500; checked cars average 86,000 miles and 6,000 miles a year. The average keeper count is about four, so condition and service history deserve close attention. It suits drivers wanting commuting or weekend touring with roof-down appeal, strong overtaking performance and more comfort than a small roadster. The Sport Plus Edition adds a well-equipped feel, while the automatic makes driving easy. Against rivals such as Audi and Mercedes convertibles, this 330d stands out for its diesel character and blend of open-air fun with long-distance ability.
