Okay, This is the East Berlin Smart Car
No, really! It's a Trabant, a car that was manufactured in East Germany (its nick-name was "Trabbi"). Every citizen got one, eventually. You could destroy it with a small hammer.
Note the black t-shirt with the East Berlin "don't walk" symbol on it. This is the car for the store we found just a few minutes before we were leaving;
it was closed. So sorry we didn't find it earlier.
