Insane is the right word. I just started the Grand Canyon endurance race and achieved a 1:12 lap time, which is mad fast but slow for the car because I can't do it justice. However, I managed to do the final corner flat out and had 230mph on the exit. By the way, the car has been available for as long as I've had GT5. I just haven't been good enough to win the Special Event in Monza because my reactions aren't fast enough.
