Found this summary of the early Mini 7 Champions in the Mini 7 News dated August 1991. It was penned by Carla Melville.
Interesting to see how many of the top drivers in this class went on to achieve success in other forms of the sport.
Great article, except it skips the first 2 years of the competition, as John Climo and Rick Constable, John being one of the founders, advised the first year was 73.
