Again... irrelevant. I have nothing but respect for the C5 Z06, the Viper and the Elise. And I'm sure that the C6 ZO6 is going to be an absolute monster. But other than the Z06... you're really comparing apples to oranges. Why? Have you ever actually driven a Viper or an Elise? Again, amazing performance cars that magazine stats say will run with or flat out smoke an NSX. But... how hard are they to drive? Would most people even consider taking one on a road trip? Can you even put luggage in them? And how comfortable are they on even short trips. My experience in Vipers (granted the old body style and not the new one) and the amazing little Lotus is that they are amazing but they will beat the living **** out of you on the street. And good luck taking one for a trip on less than perfect roads and for a trip longer than an hour. I drove an S2000 every day for quite some time but I couldn't see myself driving an Elise every day. The NSX accelerates very well, handles well, has good brakes and can be driven hour after hour in comfort. And you can actually put some luggage in the trunk.
