As someone ignorant of animal science, I admit I needed to look up what the Ralston scale is. I think we need one of these for cars.... Caterham = 1, Hummer = 10.
haha, and yes 911's used to be "3"'s and chubbed up to 7's now, although GT cars are still 5.5's. Panemeras and Cayennes come in nicely at 9's
