The 240Z along side the 280z has already made a great for the Z family in todays "classic car" market.
The 350z may miss the mark but I truly see the 370z with its powerful exterior design along its great V6 power that competes along side of those big V8 muscle houses, and can hold its own.
I believe The 370z will be desired for decades to follow as its predecessor has already accomplished, the 240Z
