New to nissan, have some questions

Hard Facts forming an opinion does not create ignorance.
Speculations from an unfound basis form ignorance.

Not to be offensive or anything and this is not what I think of both the cars, but with trying to show you the extreme differences between the two, the 240 is like a 92 Civic. The 350 is like an Lamborghini Gallardo… Which would make the 300 along the lines of an early Lamborghini Diablo
Understand the difference in performance potential now?

EDIT – hahaha without thinking about it, I just realized that the late Lamborghini Diablo GT used the headlights from the Nissan 300ZX, and put a little CF plate over the top of the headlight to cover up the Nissan Name.
