For my first contribution to this topic, some nice videos of a Z4 on the track.
Personnaly I really like the second one when the guy is about to crash into the rails. The "oh...oh...oh...oh" when approaching the rail is quite funny to listen and also when you see how close the car stopped...really lucky!!
