Important stuff first, hard touch dash (slightly rubbery coating), no cupholders.
Quite good fun, actually. Not very quick, but pretty good in 3rd, handled well but had the 18" wheels on which made it into a tramlining nightmare on white lines and under heavy braking.
First BMW clutch I've experienced in a long time that was as good as people say they should be, gearchange was that horrible slightly wobbly snicky job BMW's have had since the dark ages but seemed to work well enough.
Driving position wasn't bad, but not as good as an MX-5. Pedals were nicely set up for heeling and toeing, brakes were excellent, steering pretty good, seats less so. Body felt very stiff, which was nice. Much less flexible than an MX-5, or any other convertible I've driven recently for that matter.
The "Sport" button actually makes sense. On the motorway having it switched off makes it nice and relaxing, but once on the twisties (Snake Pass) the extra throttle response does make it more fun.
Somewhat embarrasingly on the twistier bits of the Snake I was having some difficulty getting away from a Transit Courier that was being driven very enthusiastically [1] by a local [2]. Z had no problems at all on the straights and faster corners, but the way the BMW was tramlining all over the shop under braking was enough to make me take it easy on the damp bits.
[1] Four wheel drifts in a Connect, impressive. [2] Glossop and Sheffield numbers on the van.
