Interestingly, the M3 in this month's Car & Driver comparison test with the RS5 and CTS-V Coupe appears to be Frozen Grey.
It does not seem to be the limited edition though, just a ZCP M3 in Frozen Grey (probably a la carte option in Germany).
Considering that starting in Sept. the 2-tone black/red interior is also an option, not sure how exclusive the "30" units will be...
