You're underestimating the NSX. Altough it doesn't have lots of hp's the chassis is superior compared to many sports cars (yes Corvette included). On Nürburing the NSX-R laps the same time as the Corvette C6 which has well over 100hp's more than the NSX-R. And let's be sensible and compare apples to apples. S2000 is in a totally different price range than the Corvette, not mentioning the others cars that Kai listed.
