Original Zcar Concept Sketches

Are you sure these are original S30 Z sketches? They look a lot more modern, like 280ZX...

Not really sure, they were sent to me by a member a few years ago. I've been going through my collection of stuff and uploading it...

These are 280ZX concept sketches.

What 26th-Z said. They are 280zx concept art. The same sketches appear in the 280ZX book that nissan released when the 280zx was released. (though not in colour as they are here).

The 1/5 and full scale clay models are interesting to look at too. One looks more like the S30 series, and the other looks more like the 300zx. and some are just too weird

That top left one even looks a little like a Z31.
