As with all Mercedes-Benz cars there are no deadlocks, but that's a sign of how highly they rate safety. Six airbags come standard (front, side and head airbags for both front seat occupants) and an electronic stability programme is fitted to all models. Rear side airbags are optional but there's no Euro NCAP crash test rating.
It may be a two-door, but accessing the rear seats isn't too difficult, provided you're fairly agile. There's also a good-sized boot with 381-litres of space - about the same as a Ford Focus, and the rear seats flip down to increase the load area. There's no need to stretch behind for seatbelts either - after closing the door, front seat occupants are handed their seatbelts as an electric arm extends from behind your shoulder.
