While unveiled earlier this year at the 2007 Shanghai Auto Show, the Chinese designed Buick Riviera concept car will be coming to GM’s stage at the 2008 North American International Auto Show in Detroit in January. This design, even without the gull-wing doors, sets itself apart from the current range of bore on Buick and other GM lots. We will have to wait and see if GM has the chutzpah to bring even a diluted version of this car to market.
