Will the m motor be available in Oct 02?

I really doubt it. The car in 3.0 and 2.5 trim is beginning production in September and will arrive in dealers sometime in October or November. While there will be a M version of the Z4, BMW will probably hold the release of that for approximately one year, as they have with other M versions in the past.

the m-version will be probably available at the beginning of 2004 or even later cause the M-GmBH has much to do with new m5/m6 motors
