Stuttgart is like the perfect date: not too big, not too small, well mannered, and liked by everyone; it’s a city you can bring home to mom. And it has the magic touch. When it decided to make cars, it hatched Mercedes-Benz and Porsche. When it decided to take up singing, the Stuttgart Opera won awards and became famous worldwide. When it decided the earth was getting a bit dirty, it became known as one of the greenest cities in Europe. If these trends continue, your next C-Class could be running on hugs.
