anyone in cologne koln germany?

I'm moving out to cologne next month and need to get my fix of car related fun as otherwise I may go sane.

Are there any retro clubs or garages I can hook up with? Will only have my crappy seat ibiza with me until I figure things out or buy something stupid :-)

Did find a scooter shop though so the lambretta will be shipped over.

Thanks in advance
