Considering the difference in acceleration (3.5 vs. 3.6 for Murcielago) and the cost difference ($300,000 vs. $770,000 for Maserati) I think I'd try to save $470,000 for a car almost as fast. Plus they have about the same top speed.
Somebody please tell me how the two cars even start to stack up? With a limited production run of 25 and a V-12 derived from the enzo, and the whole concept of this $770,000 F1 road car can show-up almost anything you can throw in its direction.
