The Messerschmitt KR200, or Kabinenroller (Cabin Scooter), was a three-wheeled bubble car designed by the aircraft engineer Fritz Fend and produced in the factory of the German aircraft manufacturer Messerschmitt from 1955 to 1964. The KR200 ran on a 191 cc (11.7 cu in) Fichtel & Sachs 2 stroke engine.
I spotted this one in Old Portsmouth.
Not this car, but a nice little video:

It has a lovely "face" as well.
