I know that it would be an limited run, but I remember Georg Kacher wrotes about 750 cars being build.

Translation:
As we have learned from a reliable source, only 60 pieces will be built from the M4 GTS, which are apparently already sold almost all of them!
This is particularly interesting, because even the prices are known and have signed the interested customers "blank purchase agreements" ... only to participate in the draw to be allowed!
Once we know more, we will report!
