BMW M Performance Parts are now available for the X7
"The first-ever X7 can even be had with a high-gloss black inscription at the rear so that everyone behind you in traffic knows you're driving something unique. M Performance carbon fiber exterior mirror caps are also optional. All of these SUVs can be ordered with upgraded alloy wheels up to 21- and 22-inches for winter and summer, respectively. They can also be equipped with LED projectors that show the M logo on the ground whenever the door is opened."
