i recently passed a gas station that had a small low slung convertable sitting at the pump. I could not stop to identify it, but I did spot the BMW circle on the side. The vehicle was, or appeared to be a 3 wheeler, the single one in back.
Nothing at all like the isetta. Very sporty, probably a single seater. The color was red. There were several people standing around, so I didn't get a great look. I am not that familier with BMW, I work for DaimlerChrysler, and I have not been able to find this vehicle on the net. I spotted it in Chesterfield Missouri. It was a real head turner.
