If you could watch a race between any cars in the world, what cars would you like to see racing? Where would you like the race to be and what would be the distance?

I'd like to see two of each of these cars F50, Diablo GT, Pagani Zonda C12S, Porsche 911 GT2, Ford GT and a Bugatti EB110 racing against each other at Spa Francorchamps. All of them would be just as they came out of the factory, except I'd equip them all with the same tyres, so we could really see which was the fastest car, assuming all drivers would be just as good as each other.

What race would you like to see?
