Interesting Keith , I imagine it would be hard to drive that beast slowly down the road , I always think that you are lucky in the UK that so many wonderful old and competition cars are able to be driven legally on the queens highway, wouldn't happen here - at least not in the north island.
Having only sat in a stationary one they are quite an imposing machine and when the later ones with the 8 plus litre engines fire up everybody nearby feels the earth move.
