The BMW 4 SERIES CONVERTIBLE (2013-18) 420D 2DR CONVERTIBLE 2.0 DPF SS 190 EU6 LUXURY 6SPD is a premium four-seat diesel convertible, a stylish open-top alternative to a hatchback or SUV. In the UK, it sits in the executive convertible class, rivalling the Audi A5 Cabriolet and Mercedes-Benz C-Class Cabriolet. The 2.0-litre 190hp diesel pairs relaxed pace with useful fuel-saving potential, making this 420d suited to commuting, motorway journeys and couples or small households wanting comfort with sunshine. Luxury trim adds an upmarket feel, while the folding roof gives it a special, open-air character beyond a conventional saloon. mycarcheck.com records four look-ups covering one distinct VIN, so these figures are indicative, not a broad market sample. The checks show an average private-sale valuation of £11,800, 62,000 miles, 6,000 miles annually and 1.25 previous keepers. It suits refined touring, though rear access and luggage space are tighter than in a saloon.
