Evening, In April every year we go to the Techno Classica Show in Essen, this year we drove (R129 SL600 and 996 Turbo). We attended the show for three days and from there went to Stuttgart and visited the Mercedes Classic Center, Mercedes Museum, Porsche Museum and an interesting one off visit to the Gembella factory! As we've done this now we're wondering if anyone has any recommendations/experience on any interesting/nice places in Germany to visit. It doesn't have to be car related! Berlin looks lovely but any other thoughts?
