Sorry, duffman, have to disagree with you there. Here's a few quotes from the 300ZX Enthusiast's Companion:

 

 

And, of course, in Japan, every 240Z, 260Z, 280ZX, 300ZX, 300ZX, 350Z and the innumerable domestic variants were all called Fairlady Z. As it says on the back of the 300ZX

and on the front

And here's a Nissan poster

It's not just a matter of 2+2 = ZX and 2 seater = Z. There was a 2+2 version of the 260Z and both 2+2 & 2str for 280ZX, Z31 and Z32

 

Every Z car whether 240, 260, 280, 300 or 350 has been a true Z-car. Designed by the Z-car programme and built in the Z-car factory (dunno about the 350Z, tho') Nissan Shatai in Hiratsuka City near Yokohama.

 

So don't worry 300ZX fans, our Z is a true, official Z!

 

phew well thats a relief. I'll keep the car afterall then.
