I was in Leipzig in July once. I don't know what the temperature was exactly, but I'd classify the weather as "slightly warm". I noticed that none of the buildings around seemed to have air conditioning (lots of open windows). Mercedes used to only really design for their domestic market and lagged behind on those things such as air conditioning and automatic transmissions that weren't very important in their domestic market. They finally fixed the transmissions around 1977, and it sounds like they fixed the AC about ten years after that.
