A reportage about the GENEX, the DDR-owned company, where Western citizens could order several good for their relatives in the DDR:

Interesting is the scene with the early Wartburg 353. The car has a plate from Celle/West Germany, an it was filmed there, too.
The re-founded GENEX is a car dealership nearby Leipzig. The owner collects and sells only COMECON-cars, or Western cars, which were delivered in the DDR by the GENEX.
Once there is a Bertone-Volvo for the DDR-Nomenklatura visible in the background.
If someone has a problem with the translation, just let me know.
