i think this is a fair comparison. the m coupe runs the nurburging faster than the 911 carrera. i have no trouble seeing that this could. it has more horsepower, and althought more sedanish i bet it would be very competitive and even beat the carrera. m3s in my opinion are more balanced than the oversteer prone porsches (i still love porsches) i swear if someone gets off topic and compares this to a vette i'm going to murder you. this car doesn't cost too mcuh more than a vette.
