Several decades ago:

Karl with his first ever Mercedes Ponton (his first "real" car), also a 190. This picture was taken in Istanbul: At the time, flights were not that common and the best way to get to Turkey was by car. Karl did so every summer and therefore would probably not have considered London-Istanbul enough of a challenge.

This picture was taken 27.8. 1959 on the way to Kütahya with the typical dancing bears that were still very common in Turkey at the time.
