This is my dream car :-
Sadly out of production ...
or this :-
It was more to do with the fact that they were forbidden to make aircraft
(not for the first time after the war...)
Heinkel also made a bubble car which is very similar to the Isetta , I susect it was a re use of defunct aircraft canopies from surrendering countries,
managed to find this on interweb:
OK - ordered... now month (or two) for delivery
