Blah Blah Blah....whining about it's lack of handling has been beaten up like a dead horse. Just spend some $$$ to tweak this nice chassis to how you want it to handle. Build your own M car since BMW failed to. It has the potential! Besides, most M folks still end up tweaking their rides to their likings.
All M cars are going to turbo technology so having an NA V8 is most likely not going to happen. Even if BMW added the NA v8, we would still hear Blah Blah Blah....lack of torque.
