The Eisenach car factory has an old history. They were part of BMW before and during WWII. After that the Russians deported all the cars and machines to Russia. After a trademark battle the factory continued as Eisenach Motor Werke (EMW) and build Wartburg cars, mostly based on ancient BMW technology. The last Wartburg 1991 model was the same as introduced in 1967 ;-)
Now they are building Opel cars in a brand new factory (as long as Opel exists that is)...
