My favorite little Cooper was back this year, with it's mouse-that-roared 500 cc Norton motorcycle engine. What is it that's so appealing about this little bucket? Perhaps its David-like pluck, going up against cars with many times the horsepower, I think it's more elemental than that. I think it's the "fireworks effect." There's something primal in the presence of loud noises, especially after we determine that they can do us no harm.
