drove a caterham a couple of weeks ago, it was fuckign ace. not as nice to drive as an atom, but fast as fuck. the accleration is really somthing else, and probably the closest thing to riding a nice motorbike in terms of speed thrill. id much prefer it if it had a roof, and i dont really know why it doesnt have one as standard. surely it would be faster and have less drag, but im not sure that it could be any faster. i mainly got pissed off with beeing constantly attacked by moving air, its fun at first but gets really irritating unless your wearing a helmet.
it was fast around the top gear track, but im not really supprised. the track isnt allowing the supercars to use their top end power. the reason the caterham won was becuase its so small and light, but it doesnt have that top end 200mph+ power like the Koenigsegg. i actually reckon my 550cc go kart would land a close time if driven by someone other than me.
You can get them with a roof, though they tend to heat up quite a lot in the cockpit, don't think it would be that much faster as a result, as it's already AFAIK the least aerodynamic production car, a guy told me that he was driving his in the wet and as the water trickled down his face and off his nose it flew forward and hit the windscreen because of the way the air was flowing, you can get them with an aeroscreen which is basically a spoiler stuck where the windscreen should be: http://www.carforums.net/reviews/makes/pictures/Caterham05.jpg
