I have had my eye on a ZHP Gear Knob for a long time, there so much better than the plastic factory item Z4's come with, but then found this from Germany. Its the Same as in my sisters BMW 120 (but illuminated), correct me if im wrong though in the M1 you get a similar to ZHP illuminated jobbie?? So im not sure if mine is a orriginal BMW part, but im VERY Impressed with it!!
