This is a tough call but like what
thule stated up there, M-Sport package comes with Silver / Cubed Aluminium trim or sometimes they also offer one with Piano Black(BMW Individual) which in this case it's a wooden trim... But hey, since it has an M Steering Wheel, Body kits and rims then why not get it?? RM230k only. Just search through e-bay or maybe in Mudah to replace the ugly wooden trim with a wrapped carbon or aluminium trim.
Also, the M-Sport is a bit lower than the normal 5er by a couple of millimiters and handles better
EDIT: Done some research, but couldn't find any details. You can always get BMW Customer Service to help you with this...
