Will it be an M1?   The name has typically been reserved for the much heralded supercar of the past, but BMW's M Division is reporting that they indend to build a M car based on the current 1 series platform.   350 hp, upgraded suspension, and reduce weight will separate this from the current 135i.   I would love to see this arrive in the states.   Time will tell.  BMW Parts for your one series like BMW Air Mass Sensors, Control Arms, etc can be found at AboveAllMotorwerks.com.
