This 2013 BMW 3 Series 320d M Sport Convertible offers a compelling package for open-top driving, highlighted by a particularly long MOT valid until April 2027. With 78,000 miles on the clock, it presents a solid foundation for its age, allowing you to drive away with confidence regarding its immediate roadworthiness. The M Sport specification adds a distinct visual edge to the classic 3 Series silhouette, finished here in black, which gives the car a sharp, understated presence whether the roof is up or down. Under the bonnet sits a 2.0-litre diesel engine producing 181 bhp, paired with an automatic transmission that ensures smooth power delivery through the rear wheels. This setup provides plenty of urge for motorway merging and overtaking, while still maintaining reasonable running costs for a convertible. The top speed of 140 mph indicates strong high-speed stability, making it a capable cruiser for longer journeys. As a Euro 5b vehicle, it does not meet the Euro 6 standard required for automatic ULEZ compliance in London, so this is worth considering if you plan to drive regularly within the zone. However, for general use and wider UK travel, the diesel engine offers a good balance of performance and fuel efficiency. The two-door, four-seat layout provides practical space for passengers or extra luggage when the hood is retracted. The M Sport trim typically brings sportier suspension tuning and styling cues that enhance the driving dynamics, making the most of the 3 Series’ renowned chassis balance. With five previous owners, the car has had a varied history, but the current long MOT suggests it is in good mechanical order. It represents an accessible entry into premium drop-top motoring, combining the badge appeal of BMW with the everyday usability of an automatic diesel.
