Vauxhall wants the Cascada to be thought of as a premium car, and in many ways the interior fulfills the brief. It has a swoopy styling theme and our test car had lashings of leather trim, though this was marred by some poor quality plastic on the top of the dashboard and doors. Much of the switchgear is familiar from other Vauxhall models.

The switches are nicely shaped and positioned although it’s a shame they’re so blocky and plasticky to touch. Our test car was also decorated with strips of mock carbonfibre plastic trim which arguably served to make the interior look cheaper and less classy as a whole.

There’s lots of scope for achieving a comfortable driving position. We tested the Cascada in top-level Elite trim, which includes heated sports seats with a greater range of adjustment and a four-way electric lumbar support.

One source of frustration is the lid of the centre storage unit which doubles up as a centre armrest. This is comfortable and usable once in top gear on the motorway but obstructs access to the gearlever during normal driving unless the lid is up.

The instruments are attractive, with a projected spot of light tracing the needle around the edge of the rev counter and speedometer a particularly nice touch.

There’s also an ambient red lighting scheme, with pools of light in the footwells and on the door inners activated when the doors are opened.

The front seats have quite a deep shape, and in our Elite-spec test car boasted a wide range of adjustability with a four-way lumbar support and the option to tilt the seat base as well as the back rest angle.

In Elite trim the leather seats are heated, and you won’t find the same design in other Vauxhall models as they’re designed specifically for the Cascada.

The highest Vauxhall Cascada comfort levels belong to Elite trim derivatives, which feature dual-zone climate control and both heated and ventilated seats as standard.

On the whole the Cascada feels as refined as a fixed-head saloon car, but without the optional acoustic roof wind noise can become an issue as speeds increase.

A foldable wind breaker can be mounted behind the front seats to reduce buffeting from the wind when the top’s down, although this means there’s no access to the rear seats for extra passengers.
