It has been a long time ago, as I met some interesting people at the "Retromobile" in Paris, discussing with the editor of the book(s), "Constructeurs sans patente". Since this meeting in 2012, I am in very close connection with some of these persons, mainly interested in French specials. I can say by myself, I am an negligible and ignorant Rookie in this group of car-maniacs. They know about so many French specials, never seen and heard about before.
Got two pictures from them, about the Renault by Jacques Ego, some time ago.
I mainly take books and magazines (trust me, enormous library!), to solve puzzles,... As also my well-organized car data collection on my PC.
Don't like the internet. Not my thing. Takes too much time, with more than many wrong results. I only know a few car-pages with reliable content.
