Some need to understand that many people can't afford a TT. Rather it be the higher maintenance to properly maintain and keep the Z running, the insurance, the overall price... It's a combo of all these. Currently, I am satisfied with my NA. Sure, I'd love to have an extra 100hp at my disposal, but I certainly don't need it...it's just on my wish list :) Like you said, a Z is a Z rather it be a TT or an NA. I still manage to turn the heads of many people while driving.
