Have I understood you cryptic answers correctly:
It is a VW
It was built in Germany
You do not know the make of the engine so this is not relevant to the puzzle
It was not a VW factory prototype
Is the body customised by a German coachbuilder?
I cannot find any cryptic answers:
Factory VW prototype?
I answered with: No (cryptic?)
Custom engine swap?
I answered with: Sorry, I do not know anything about the car's engine,.. (cryptic?)
A VW built under licence outside Germany?
I answered with: No (cryptic?)
So, it isn't a VW?
I answered with: It is a VW (cryptic?)
