Isuzudas put together a video for the 2010 Isuzu Owners Meeting already.
http://www.youtube.com/watch?v=wTAkVwGDbjoThe panning is a little too fast for the camera to keep up for a smooth moving image. Pause and you can get some pretty clear views. Also, plenty of slide show stuff.
I see two Bellett GT Fastbacks. One is the regular in the show field. There are usually two regular attendees in the show field. The second I spotted was parked in the Front Row Club Members area, which would be Imura's (Jerald) car that is being offered for sale. So he is not taking one from a remote location on commission, he has one on hand to sell. I doubt this is one of the ones that was a regular show attendee. So if we take the two regulars, the car offered at Jerald, and the two that were being offered on Goo-Net, that would make a minimum of five running Fastbacks in existence.
He did another version two days ago:
