you can't base your argument on how fast the NSX is because you saw a Best Motoring video and an NSX won. If I remember correctly there was a thread on here (or was it another forum) that said how it was unfair the S2000 lost to the 350Z on another Best Motoring video, by the same standards, you can't say one car is better than the other by some video.
The corvette is a GREAT car, why? Because for that price, you simply cannont find a better performing sports car. Then again, that is why there's too many corvettes on the road, and an NSX is much more of a head turner.
