this car is undoubtly one of many home-built cars form the East-bloc. Mostly built from WW 2 wrecks, with lots of IFA, Wartburg and GAZ parts. Looking at the wheels, the chassis could very well be from an early VW Kubelwagen, and the rest is a mixture of parts found everywhere, The Mercedes-Benz star on the front dosent meen that there is Mercedes-benz parts in the vehicle, but only, that the builder just found that star somewhere. But unfortunetly it is not possible to find out exactly what it is, unless you find the coachbuilder. The other cars is much easier to put a name om: The bus on the Right is a Phänomen , and the small car on the Left is an IFA P 70, which later were redesigned and got a new name: Trabant
