Thanks you all! It was brought to the Soviet Union after WWII and used as a farmer's car for some years, this is also the reason why it has tractor wheels and a trailer hook.
Rhineland-Palatinate OMOFERINA It's a 1939 Maybach DS 8 Zeppelin Thanks! It's been such a long time since I saw that. Next time I get to the area, I really have to check whether they got any new cars in the museum.
I also shot a Zeppelin once - at Zeppelin museum in Friedrichshaven.
