Parkers overall rating: 4 out of 5 4.0

Mercedes spends many hours and money making sure that every switch works with the same precision. This means each and every button presses in 1.4mm to make it work and it’s this kind of attention to detail that makes the E-Class Cabriolet's driving seat such a great place to sit.

The ergonomics are spot-on and every type of driver can find the ideal position thanks to an electrically adjustable steering wheel and seats. All of the dials are clearly visible and the latest E-Class centre console is much simpler to navigate, even if there is still a profusion of buttons for the stereo and ventilation.

The optional satellite navigation screen is big and clear, but the layout of the menus and rotary controller on the centre console take some time to get used to.

But like much of the exterior, here's little within the cabin that gets the pulse racing.

Mercedes E-Class Cabriolet comfort is really good, thanks to being longer, wider and a little lower than the CLK model it effectively replaces.

These gains in length and width show up in extra cabin space, though adult rear seat passengers will still find it pretty snug for their knees and legs with taller front seat occupants in place. However, rear headroom is decent for this class of car, while those in the front are very well catered for.

All models come with heated front seats, but Mercedes’ clever AirScarf system that blows warm air onto the front seat occupants’ necks is an option. So far over 80 percent of E-Class Cabriolet customers have ticked the box though.

Mercedes’ AirCap, a little spoiler on the top of the windscreen that is automatically raised at 25mph and lowered again when dropping under 10mph, is a worthwhile addition.

It doesn't look very good, but works incredibly effectively - we experienced little or no discomfort during a three-figure open-roof cruise - and you can't see it from inside the car.

With the acoustic roof in place the E-Class Cabriolet is very quiet, almost matching the coupe’s refinement, and only the occasional murmur from one of the smaller capacity engines can be heard when cruising.
