Not sure if I saw the same 1, I distinctively remember it was a Brown colour though and the boot lid was dented inward in a triangle fashion. The steering wheel was no longer original replaced with a SAAS item from memory (8 years ago this was) and I don't think it had the standard wheels anymore.
I recall it being parked near my high school which was in Caulfield (Glen Eira College) and I later saw it being driven in a Chadstone car park.
I remember dragging my mates outside of school boundaries to go see it, I'm glad I did that now. I've never seen another 1 in person. I remember speaking to Warren at Zworx about it, he mentioned the owner wasn't selling it. So I figure it may have been the same car.
I do wonder where it is now, I only hope it wasn't scrapped.
