I saw one at traffic lights at St.Ives (northern Sydney suburb). I was two lanes away from him, and by the time I put my car in gear (I always have the car idling in neutral whenever stopped at lights), all I heard was a chirp of the tyres, some sort of exhaust note (not overly loud) and he was an easy two hundred meters down the road - and then had to brake sharply to turn left into a sidestreet ! It was an AMG, and it was impressive. However, I believe they're about $80K. new. Regards Styria
