So the F10 550i can take an M3 on street but not on track? Then the M5 is a beast for sure... After listening to the clip of the F80 mule the exhaust sounds similar to the M5... So the engine just may be two cylinders cut from the tü and imagine this - a baby 650i m-sport coupe ///M ified - M4 could be badass just hope it's not as bloated and heavy as the mule looks
