The Sky is the perfect new face for a suddenly energized Saturn. The General Motors brand, known for lousy cars and great customer service, is poised to deliver greatness on both counts starting with this convertible, and the excitement among business managers and product people is palpable. It all starts with the Sky, followed closely by the new Aura sedan, an eight-passenger crossover vehicle called Outlook, a hybrid Vue Green Line sport utility vehicle, and stylish replacements for the Ion and the Vue. In fact, serious money is betting that a derivative of the fun Opel Astra will replace the Ion, a dud of an econocar that you might not recommend to your worst enemy. That would follow form, as Saturn is basing its revitalized lineup on Opel vehicles, or, for you Brits, Vauxhalls.
