Hi there,
nice to read about a growing community in NRW, Germany. I'm from Duisburg, thus we're almost neighbours. It's funny that we are similar age (I'm 30) and share the same profession, Raphael. I'm also industrial engineer.
I have a Europa S2 from 1969, which used to have a historic road registration, but since 2011 is only used for vintage racing. Thus, I'm quite experienced with most of the technical aspects of the car. But I'm not an expert on originality, as my car is heavily modified.
Maybe we'll meet sooner or later.
Best regards
Stefan
