You're right about that one. The perception most people get with the NSX 290HP is that it's too close to the CLS 260HP, and yet it's 60k more. Hell, add some basic mods to the CLS and you have well over 300 hp (Not that HP is all that important though).
don't get me wrong, I'll probably buy an NSX when I can afford one, but upping HP to 350HP would not be bad to really set it apart from the other models. It sure wouldn't hurt??!
