It was the standard knob through December 2000 on any M5 with the Titan Line interior trim. Because it had very poor wear resistance, BMW discontinued the part at that time and began offering the all-leather knob in its place. It is no longer available.
Earlier cars with the defective knobs could get them replaced under warranty, so many cars that originally did come with them will have the all leather replacement knob.
