Living in Utah, we haven't been exposed to the matte colors, so I would be game for any of the matte colors for MY2011.
By the way, I am taking March allocation for a 2011 E92 and I am trying to find out more about frozen gray and performance packages through the dealer. I was told that I could do any color for an additional $4000 if the matte colors are not available in the USA.
2011 E92 M3 - Space Gray, ZCP, Akra Evo System, aFe filter, PC Stage II Tune & more!!!!
