Not missing much there. I assume the media pack pro includes Navi pro and the big monitor.
I would have traded the adaptive suspension with the standard M suspension, as this is quite comfortable. You won't miss a softer mode. For the saved money I'd buy the rear view camera.
Also I'd traded the electric adjustable seats in something else, like 18" wheels (if not standard in the UK). If there are two drivers in your household it might be sensible to keep it though.
I'd definitely pick the 20/40/20 rear seats and the storage pack, especially if this is your main car meant to cover all your daily needs.
Allthough I normally choose leather seats, I found the standard M interior very attractive, so I kept the Alcantara/cloth combination. Leather is more practical though.
Other than that you seem to have made smart choices
