hrm... i used to be the biggest z32 fan... actually i still love them more than most cars on the street and i will get one definitely in the future...
but hrm... going further back... doesn't the X in the ZX label denote boost? Like they only placed it when the car had a turbo option. For example, the 280Z had no option for boost... but the 280ZX did.
The ZX and Z labels also have to do with autocrossing and touring and how the ZX was a fusion of the two.
Also was the flagship at the time... also the Z31 the 1984 DATSUN anniversary edition 300Z(X) came turbo pimped out to the fullest... it was the flagship of the flagship back then, even the key was gold plated.
Mad rumors on the nissan boards... I used to be all over them, but they say that the reason the X wasn't placed in the 350z is because it was never intended to be a true Z... a Z, more specifically a ZX is supposed to be flagship nissan.. That flagship is now the skyline, so they have no need for the X. Either way dudes an idiot for calling ur car "not a Z" that is disgraceful... your car is more a Z than the 350 will ever be. For some reason the VQ doesn't embody that same Z-ism that the other gens did... or is it just me? Just something homosexual about it lol.

but back to the main subject.... ANY ZX is more of a "Z-car" than those damn VQ's... coming from a Z enthusiast.
