jeez, a friend in Romania (female, go figure! :) has one, a "licensed" Citroen....
"Oltcit"
Says in the article, they had a flat twin and flat four aircooled engines, and even torsion bar suspension!
Must study more, I just found out 2 minutes ago. I wonder if she could take some pictures for me, especially of the engine. Or if she could pull the engine, disassemble it and measure everything for us.. lol..
