Editor's note: If you have friends who are cool enough to debate with you which American muscle car is King, you've probably argued over whether the Plymouth 'Cuda series was better than Ford's Mustang, Chevy's Chevelle or Camaro, or the more recent Dodge Hellcat. And you may never definitively solve that all-important question. But in the category of "life's a journey, not a destination," have fun debating and showing off your new 'Cuda wallpaper. Enjoy the ride.
