Hello and thanks, I added comfort and technology packs. Having had the matching door cards in my last Z4, I just fancied a change and in some ways I prefer the all black doors and yes, you can have any of the interior trim colours.
The dealer I used for both M40’s was BMW Boston, Lincolnshire and the agent was Emily, really easy process, no haggling just the best price from the off, they’re into volume sales that’s it.
