2 Ozi: I forget mention black kidneys. They are already mounted.
2 Rikx: that would be nice. I visit Munich aprox 5 times per year so it is not problem to plan a route. I can take friends of mine who owns 1M also.
To all others - thanks for warm welcome. Appreciate your support. I will update this thread during next months.
There was one thing what surprised me when preparing my mods. I live in Czech republic which is close to Germany. And I expected lot of suppliers of these parts should be available in Germany. Bu they are not. I have to import almost 90% of things from USA and Hong Kong. It is weird especially when you consider buing parity is very strong in Germany, also it is origin of BMWs and huge amount of ///M cars drive there.
