I’ve just been pondering this. To me there are several ingredients to make a car a true classic, and the Zed ticks all the boxes.
A niche market – the Zed is not a mainstream car. It’s impractical, noisy, and a bit extreme for most people. Few would consider one as their daily driver.
Low production numbers - there are comparatively few around. It’s pretty unusual I ever see another Zed when I am on my travels. No new (350) Zeds are being made.
Unusual styling – most modern cars look pretty bland to me. The Zed is very distinctive. It’s never going to win a beauty contest but it is striking.
Speed – unless it’s a very quirky or ground breaking design I think most classics need to have performance credentials. Classic performance cars are usually lauded for the way they drive rather than their outright speed. I think the Zed ticks that box.
I believe that in a few years that the 350Z will be revered as one of the last of a dying breed, namely the hairy chested sports car. I will be proud to say I owned one.
