I attended this event last weekend and saw some amazing minis -
they had 22 in one race along with many other period cars on the grid.
Saw 70's and 80's F1 and 2 cars racing as well as pre66 touring cars - a few videos on you tube
As we would expect mini's held their own against more powerful contemporary cars
Also a Mk1 Cooper on sale from an auction dealer for £79,000 !!!!! (yes - £79,00 !!!)
