Best suited to couples or drivers wanting weekend escapes and trips, it offers strong performance and a special open-air feel. It is less practical for child seats or luggage, and running costs deserve consideration. Against Audi A5 and Mercedes E-Class convertibles, the BMW feels composed, sporty and notably distinctive overall.
