As you can see in the thread that is mentioned it is possible to get a German M&M CC but it is a little bit of a hassle because you have to have a German bank account.
Opening one can be done. Probably the cheapest way is opening a DKB online account. There is even a "special" offer that will get you some miles.
And if you take the M&M gold CC you also get a decent amount of miles for your efforts.....
