This is the old Horch factory in Zwickau. Horch were one of the four rings in what’s now the Audi logo. They’ve refurbished the place since.
This is a pre war Auto Union V16. They were quite a thing at the time. Still are, come to that. Driving one really quickly requires gentleman’s apparatus the size of watermelons.
This is a Trabant 601. It is less of a thing.
They all have something in common.
Both the cars were built in the Horch factory.
