I remember one particular car, a mid engined supercar built by a Japanese fellow. It had a Countach V12, and the styling was almost origami, lots of complicated folded and curved surfaces. Looked amazing but can't remember what it was called and haven't been able to google it. I'll keep trying.

I remember that (vaguely), like you I can't remeber what it's called but there's a film with Wesley Snipes and Sean Connery in (possibly called Rising Sun?) set in Japan and someone crashes one in that.

The car in Rising Sun was a Vector.
(Vectors were American with a V8, although a handful were built with a Lambo V12 when the company was taken over by Indonesian company Megatech.)

I don't recall the film Rising Sun but I know for sure the Car I'm thinking of wasn't a Vector. It had much more complicated surfaces and I am sure it had some bits overlapping itself a bit like an armadillo

It's not this, err, interesting looking thing is it?

Yes! That's the one, thanks! I remember it with different wheels, as in this pic, perhaps they are covers, but it was that same odd green that you posted above. You just reminded me how the nose really wasn't its best part... and time hasn't been kind to it either.
