We see a high-powered executive walk out of a large corporate office building and into a Fiat, driven by a corporate chauffeur. Then the chauffeur drives like a race car driver around the city, looking like an obstacle course and an exciting chase scene from an action movie, with lots of near misses, etc. Then they reach their destination, and the executive gets out of the car and walks into some big corporate skyscraper, and the slogan is: "Going places, by executive Fiat." (Or: "Moving up in the world, by executive Fiat.")
Then a future ad in the campaign could show the same executive give the chauffeur the day off, and he'd get involved in a car chase or a race, with slogan: "Action, by executive Fiat.")
