Here's why it doesn't matter that the car's not one of the three* 330 P4's originally built. On a track, heavy in a braking zone from 200 mph, with that utterly sexy V12 drilling a hole in your eardrums as you blip the throttle to downshift, you've got to be as precise as a neurosurgeon to make sure you're in the right gear.
All while you're imagining the GT40s menacingly filling your mirrors.
*There was also one 330 P3/4 produced. Some count it. Others don't.
