Garage

The Fuhrerbunker houses a garage where the officials' cars and Speermobile are parked. This is the place where Himmler and Fegelein have meetings with the Antic dealer Albert Speer to discuss several ways of getting the nerves of H and to buy antics from him.

The garage seems to be Kempka's hideout, since he hasn't almost any scene in the film saving the gunsche phone conversation and stairs.
