I'm not surprised. This was extremely difficult. I saw that it was a right hand drive car and guessed that it was probably some sort of kit car, so I did searches for rare British kit cars which was fruitless. I then searched Australian kit car manufacturers that led me to a Wikipedia entry listing Australian motor manufacturers. Googled images of every (unknown to me) listed car maker until I got a hit. Took most of Monday to find it though. If I had not found it under Australian carmakers, I would have tried South African kit car makers. After that I would have given up. According to my research this is a pretty rare car as only 12 were ever manufactured.
