I have to say I prefer the 370z nismo over the original model. Do I think its worth the extra money it costs?.... probably not, but as long as he enjoys it thats all that matters.
You could always buy a 350z waste money wrapping it in turquoise, supercharging it for 5 mins only to dismantle it all and sell it on at a loss, thats gotta hurt the wallet more I would say.
