saw one on my street (kensington church street) today, being driven by an older gentleman with white hair, and he had a passenger - and boy did they look tight in that thing. first time i have seen one outside of a static display. it looked other-wordly and was stopping traffic. the sound was nothing too special though, no where near the idle rumble of a murci or an enzo. it looked easy to drive too - the guy didn't appear to be struggling with a heavy wheel etc. anybody driven one?
