The E-Class isn't cheap and suffers from heavier depreciation than some other four-seat convertibles (such as the Audi A5 Cabriolet) but it's far from a money pit. The diesel engines are pretty economical by the standards of the class, and CO2 emissions are also competitive. Even the range-topping E400 twin-turbo petrol can average more than 35mpg – in the official government tests, at least.
The E-Class Cabriolet is supposed to be a premium product, but its interior doesn't quite give that impression. Everything is solid and there are some nice touches, but too many surfaces are disappointingly unappealing. That said, the E-Class Coupe (on which the Cabriolet is based) received above-average marks for mechanical reliability in the most recent JD Power ownership satisfaction survey.
Mercedes-Benz E-Class Cabriolet safety & security
This is the first Mercedes cabriolet with headbags to improve protection in a side impact. The car also comes with roll-over protection, and a reinforced windscreen and central pillars to add stiffness to the structure. There's also a driver drowsiness detection system and a pop-up bonnet to protect pedestrians. An 'intelligent drive' system uses a camera mounted behind the windscreen to view up to 50 metres ahead, scanning the road for obstructions.
