The leather and Alcantara-clad driver’s seat in the C 63 S Cabriolet is heated as standard and, because it’s motorised, automatically slides itself forwards and downwards when you fold the backrest out of the way in order to get access to the rear seats.

Like a great deal else about this car, it easily satisfies the particular requirements that are likely to be made of it as part of its service in a sporting four-seat convertible.

Wouldn’t it make more sense to push the hood lever down to fold the roof down, and pull it up for the opposite?

Entry to the car is via a long door that can be a bit cumbersome in tight parking spaces.

The act of getting into the back seats is much easier with the roof down than it is with it up, and once back seat passengers have successfully boarded they’ll only find sufficient space to get comfortable if they’re below average height.

But in every one of those ways, the Mercedes-AMG is entirely typical of its four-seat cabrio breed; a Rolls-Royce Dawn is a little easier to squeeze into with the roof up, but it’s not night-and-day different.

The car’s dashboard layout is common with that of the C 63 saloon, and so is the driving position. So the primary controls are well placed and the steering column is widely adjustable, while the conventional analogue white-on-black instruments are gently suggestive of enhanced performance and also very easy to read.

The central colour trip computer display gives you digital temperature gauges for oil and transmission and lap-timer functions among many other things, and the tactile quality of the materials in front of you, from the downy suede covering on the steering wheel to the knurled metallic climate control switches on the centre stack, is top-notch.

The car’s cloth hood is fully automated and operated via a chrome-finished lever conveniently placed just ahead of the cabin’s centre armrest.

It takes less than 20 seconds for the roof to be either lowered or raised, and the operation can be carried out while the car is moving at up to 31mph.

It emits only a discreet electrical whirr as it cycles through its action and stows away invisibly in a compartment immediately above the car’s boot.

With the roof in place, the C63’s boot, at 360 litres, is as large as that of an average five-door hatchback, and access to it is reasonable through a wide aperture.

With the roof down, a fold-out storage bag cuts available cargo volume to 285 litres, and that makes sliding bigger loads into and out of the boot tricky.

So the C-Class Cabriolet’s practicality shortcomings are predictable, although they’re easily negotiated provided your requirements of it are realistic.
