The UK configurator
www.bmw.co.uk came back up with updates this morning.
One addition I noticed on the M Sport is the new display of BMW Individual Trim XE9 -- Black Leather with Braided Pattern. Here is a close-up sample from the X5 Individual Brochure.
I personally like BMW's burl walnut wood trim (yes, even on an M Sport), but the Individual leather trim might be a good alternative to the hex aluminum for those willing to pay a little extra.
