Ah, the Lotus/Caterham Super 7. Had a chance to buy one quite a few years ago. Ended up passing on it (needed a new front fender, which is no small thing on a 7), but still have fond memories of the experience. With a straight-8 under the hood, it's like a Titan rocket strapped to a roller skate, 'coz there's precious little weight to slow down the horsepower!
I saw the new lotus at 12-Hours at Sebring last year. Pretty impressive. Have you seen it? I almost bit but giving up all that tourque in my Vette would be tough.
