Thanks Mark. As the club president I had to choose my selection of what I considered to be the best car at the show. My pro-buggy bias shone through when I selected the yellow buggy because it is a Manx clone, classic and unmolested. Richard.
It's hard to see but the rear cage on the yellow buggy is actually connected to the roll cage through the 'firewall'. A good idea I think. I might use that in the design of my rear cage.
