The latest from the CarBuzz spies shows a Mercedes-Benz vehicle that we definitely hadn’t expected. It’s a GLC electric vehicle prototype with a difference. This one is longer than a standard GLC-Class, and that’s because it’s going to get a third row. The GLC has been stretched before, but this ungainly Merc would be the first seven-seater for the model and its size shows exactly where Benz intends to sell it.
