Mercedes-AMG has been spied while putting the finishing touches on the next-gen GT Coupe in northern Europe. By "coupe," we mean that in the truest sense of the meaning since this prototype isn't the confusingly named GT 4-Door Coupe. The Porsche 911 competitor from Affalterbach was seen resting between two test sessions, flaunting its sleek production body painted in AMG Green Hell Magno. As expected, it looks like an SL with a fixed roof.
