And the point goes to ChanceHuncha.
Besides the Flickr page, I did see a page in Japanese which indicated Andrew Spence was the owner and builder of this car.
This car appeared in an episode of the TV show The Scarecrow and Mrs King during 1984, before it was modified.
Mr. Spence also built an SC100 using Ford Sierra power. I have seen no indication it was the same car, but there is not a lot of information available about his vehicles.
