A mate of mine always has a small selection of Cobras in the shop, and his own. He is working on all models since 35 years. Fly to Köln and drive 30 min (Windeck). He speaks english well enough to explain. Check
Willkommen bei Cobra Corner
Probably the most decent shop for Cobras you can find in Germany. If this is too far, I can ask him for Cobras near München. And the german Club has one or two members in Switzerland.
And while you are checking, near Soest, a short drive from Dortmund is a dealer. I wouldn't buy from them, but I am biased. I build me own.
In Europe the RAM is very popular, and a very good car. I had one myself, and CobraCorner has one. His is an extremely quick car. And Cheng-Lim from Thunder Road cars in UK is racing one.
