This movie clip of an Australian Twini was flashed over to me, and I understand it was taken at the Huntley Hill Climb in New South Wales last September. The car is said to use twin Cooper 'S' units and weigh 550kgs, but that's all. When you watch the video you'll see it goes off like a rocket but the climb seems to end not quite so good unfortunately. Any further info would be much appreciated!
