The Mazda Miata deserves the "revolutionary" change that it's undergoing. After all, this brilliant little roadster is 25 years old. If nothing else, it's time to celebrate the car's success and popularity. Mazda agrees and has finally put out the "save the dates" for the party: September 3. On this day, we'll finally see the skin of the lighter, nimbler, more rigid roadster. Prepare the drinks and get your racing helmets ready.
