I always remember them racing on the Birmingham street circuit they were quicker on the straights than the f3000 cars of the day even though they couldn't out corner them.
Every touring car series they entered had the rules changed to outlaw them as other manufacturers were not happy even though could have built a similar car if they had of thought about it, best time for road cars back then as to enter a race series they had to build similar road cars, most racing and rallying now have vehicles that haven't been built as road cars so I can't get interested in it anymore
