The BMW 3 SERIES CONVERTIBLE (2007-14) 320D 2DR CONVERTIBLE 2.0 177 M SPORT STEP AUTO is a premium four-seat drop-top, bringing executive-car comfort to open-air motoring. In the UK used market, it sits above mainstream convertibles, appealing to drivers wanting a smart badge and more everyday polish than a roadster. Mycarcheck.com records 1,141 look-ups across 351 different VINs, a substantial sample for this specific model. Checks show an average private-sale valuation of £5,000 and average recorded mileage of 107,000 miles. Owners averaged five previous keepers and 6,000 miles annually, helping frame individual cars; condition and service history remain important, however. The 320d suits commuters and couples seeking a long-distance cruiser that can also handle journeys; its diesel engine can be economical, while the automatic gearbox makes traffic easier. With four seats and a folding roof, it is more practical than two-seat rivals, though rear access and luggage space are limited.
