I've always been fond of the Messerschmitt KR200 microcar,
I just noticed that it looks uncannily similar to the 1956 Royal Enfield Bullet Dreamliner prototype,
which unfortunately, never saw production. I imagine someone savvy with fiberglass could crank out a fairing for the modern Bullet that looked like the Dreamliner. Maybe Classic Motorworks could add it in their lineup of accessories?
