Name this little car for one point please.
Brütsch Rollera (1956-1958). A single seat, 3-wheeled roadster, powered by a single cylinder 98cc Fichtel & Sachs engine driving through a three speed gearbox. Top speed was around 80 km/h (50 mph) and eight cars were produced. Also built under licence by Air Tourist Sàrl of France.
That final piece of you're answer gives you the point.
It is indeed the 1958 Rollera by Air Tourist Sàrl
