In my opinion the original NSX is a great looking car. That said the next NSX should have the following changes:
1) HP, at least 450.
4)Shape, While keeping similar lines to the first NSX, change the car. No one should mistake the new NSX for a 91 NSX. No one should be able to just take $5000 and buy a few parts from the new car and make the older NSX’s look like the new one.
Well, the 360, 996TT, ZO6 are all considered to be awesome performance cars and they don't even cross the 450hp mark. Not to mention that the 996TT and 360 far outweigh the NSX in the price department.
All I want is a 3.5 V6 ($87,000) that will push somewhere along the line of 360hp, similiar weigh, better drag coefficient and I will be happy.
