I was at our local outdoor go-kart track putting laps on Kyoko, and her previous owner showed up in his new project car.
The Locost is basically a Lotus Seven clone, powered by a turbo Miata engine. (1.6, I believe).
I just saw in action today, and man was it fast! Hopefully Peter will see this post and bring up some video of his car, so we can post it here.
