There was an article that discussed the birth of the 240SX related to getting back to the simple nature of the 240Z, but I can't find it at the moment. If this thread is locked by the time I do encounter it, I'll email it to you, if you'd like (not being argumentative - it was just an interesting article about the progression of the Z car).
"When you say this, will you be surprised if your arguments seem to move about instead of staying put? And will you accuse me of being Daedalus who makes them move, though you are yourself much more skillful than Daedalus and make them go around in a circle? Or do you not realize that our argument has moved around and come again to the same place? [...] Or do you not remember?" - Socrates
