For my sins I have demo’d a Quash, a 1.5ltr diesel top of the range black something or other, the new shape not the older one you seem to be looking at.
Firstly, it’s a nice place to sit, the ergonomics and seating are really nice. It’s high enough driving position to see over most cars, but not all. So what you end up with is seeing a lot of rooflines and roof racks.
Inside sizewise it’s nice enough, I’d say not much bigger than a normal family hatchback the size of a focus or similar. The boots a bit short, wide but not deep but way more than enough for shopping and crap like that. The rear seats fold flat and if you squeeze a little a bike with wheels will go in it, my CXer did with the front wheel at right angles to the frame.
Driving, nice enough, spritely, feels light to drive, quiet very quiet actually.
I’d say, some will hate me for this, that the quality of the cabin is on par with my Volvo XC60, maybe not in density but the fit and finish and quality is really very good.
I’m not buying one, though.
