The NSX is a nice car. You can drive the hell out of it, and guess what? Its a honda. Wont set you back $6000k every 7500 miles. And for those of you who dont think its a true exotic, how many do you see everyday? I would buy the NSX.
In that sense the honda is a honda, and a porsche is a porsche seems to carry a bit of status with it. I dont buy too many things because some people "say or claim" it to be better. Ill buy what: after doing research, is found to be more suited to what I am looking for.
I would drive both, and see which one I like better. That way no one can contest your decision and you know you made the right choice. I think its crazy to to base any kind of decision about anything without knowing or trying the product with info based purely on other peoples claims (who most likely never drivin one before).
Both are nice cars, which one is right for you and your money is your decision, and should be respected.
