BMW 4 SERIES CONVERTIBLE (2017-20) 420D 2DR CONVERTIBLE 2.0 DPF SS 190 EU6 M SPORT AUTO8
Buyer's Guide & Data from our Checks
The BMW 4 SERIES CONVERTIBLE (2017-20) 420D 2DR CONVERTIBLE 2.0 DPF SS 190 EU6 M SPORT AUTO8 is a premium four-seat convertible, offering a stylish alternative to a family hatchback or SUV. Its folding roof brings open-air driving, while M Sport trim gives it a purposeful, sporty look.
The 2.0-litre diesel and eight-speed automatic suit relaxed motorway journeys and regular commuting, as well as weekend trips. It is best suited to drivers wanting comfort and style, couples or smaller households who can manage limited rear-seat access and less luggage space than a saloon. Against the Audi A5 Cabriolet and Mercedes-Benz C-Class Cabriolet, the BMW is known for a more driver-focused feel, strong refinement and a balance of everyday usability and open-top enjoyment.
