Both singer John Cougar Mellencamp and the S-Class Coupe are 60 years old this year, but for some reason, Mercedes-Benz is only honoring one of them with a special anniversary car. I know, John, it hurts so bad. The CL‑Class “Grand Edition” (starting at $157,300) includes exclusive designo paintwork, high-quality designo leather appointments and 20-inch wheels. Factor in the standard AMG Sports Package and engine options that can crank out up to 517-horsepower, and it gets easy to see why Mercedes left Mr. “Pink Houses” over there to fend for himself.
