Lamborghini Reventon
 

Subzero, without a doubt! 8-)

Cool but not subzero!!!!:-)

Subzero...too bad it couldn't have had slightly more exotic internals...(not that the LP640 is exactly a slouch)

This is the car that a guy like Batman would definetely own, thats why it is subzero without a doubt....

Yes, this deserves to be subzero.

Sub Zero but 2 problems.
1. They've only made 20.
2. It costs 1'000'000 Euros.
But apart from that, the Performance is fantastic & I'm a Huge Lambo fan.
