Not really, but I did recently have a 350z owner tell me that 03 was the first year of the z. Imagine that being to to you. Unfortunatly I was not driving my tt , so I did not have my conclusive evidence with me. But it was fun telling him he was wrong, even though he was convinced that he was right and so was his little chicky. Anyway, ya if you drive a z 240 to 350 you should at least be able to recognize the others in the family!!!!!!
