For more than half a century now, Mercedes has been skilfully blending luxury and space in a large estate that proudly wears that prestigious, three-pointed star. In fact, there have been five generations of its big, family wagon so far, of which four have been dubbed, in one way or another, the Mercedes E-Class Estate.
The first wasn’t called that because the E-Class name didn’t exist back then. It was the model that set the trend for something spacious and classy, though, and in the process, it left the other premium producers floundering.
