The S30 is still incredibly under valued here as a world class performance car, I'm afraid that most Australians value a car based on what they paid for it rather than any real evaluation of the physical car itself. That and the enduring fallacy that somehow euro cars are better and that only those who can't afford one settle for second best, a Japanese car.
I'm afraid that as far as your average 'car enthusiast' here goes most of them are 90% image influenced and just follow the mob
Do and don't agree, early rotary coupe's are particularly valuable in our market and more appreciated here than they are in say the US / North American markets. I think S30z's have been slow to appreciate yes, but in the last couple of years things have certainly changed. The old "Jap Crap" tag is slowly becoming a relic of the past. Frankly I'm surprised by the increased interest in recent year, even in some lesser known Japanese stuff. Websites like Speedhunters have put a magnifying glass over these makes with a younger generation.
Just the other day I was at the Cinema and saw an Video Arcade Machine with an S30z on it, you see them more and more in pop culture, music videos, movies, tv programs, automotive programs (recently wheeler dealers) etc..
Funny enough when some complained that I was posting international cars for sale in the third party car sales thread etc.. I decided to split the thread into the global market and local market threads. Although not many have replied on the global thread I can tell you it's 1 of the most popularly viewed threads on this site...So there is definitely interest in what's happening in the market on a global level.
