It doesn’t take someone of high intellect to understand that wagons aren’t as sexy as sports cars. That’s never been the case and that’ll never be the case unless automakers completely reinvent the way we look at these cars. But, just because they don’t look sporty in the traditional sense, that doesn’t mean they can’t perform like a sports car. Take the case of the 2015 Mercedes-AMG C63 Estate. On the surface, you won’t mistake it for its two-door brother. But, pop open the hood, and it becomes a different story.
