Big thread bump from 2010, but I managed to meet the owner and got a ride in this car recently in Japan. The owner Tomitaku San was a great guy and he spoke about as much English as I did Japanese, but we had a few laughs as he drove it through the Japanese country side. Will share some videos soon.
Also the original SpeedHunters link in this thread is broken, but you can still find the article here:

Although SpeedHunters is kind of on hold or taking a hiatus as of late. At least the images and content is still there. I also on the same trip managed to meet Dino Dalle Carbonare who wrote the article back in 2010. Which was also great.
The trip was part of the S30 World Team 2025 expedition to Japan, of which I have become part of, to try and help promote and celebrate the S30Z worldwide.
