Hi TC.
When I first had the car I had exactly the same thoughts as you. I've now done close to 7000 miles and love it. It really improves after run in and above 4000rpm is amazing. I also have Magnetite Grey and love it. (although sometime wish I gone sapphire blue...)
You can buy some
tinted stickers to dim the airbag light (it is annoying, as are the green LEDs in the toggle switches).
I
think you can switch off the headlight rotation in the car settings.
I have disconnected the fake engine noise. makes the car so much nicer to live with day to day.
I have also bought some sound deadening mat and fabric tape to reduce some of the road noise and general rattles. not installed yet; will update when I do.
I get about 34 mpg, but I generally do fast A-roads, not much round town stuff.
The reversing camera is a god send!
Anyway, get through the 1000miles run-in and then enjoy!
edit: I also agree re: the AC. and in auto it will never use the screen option. I also find the AC to either be freezing or super toasty. Weird...
