http://www.autoblog.com/photos/battle-royale-gm-vs-chrysler/1121964/At first we thought the idea of a merger between General Motors and Chrysler LLC was laughable. We still do, but persistent reports to the contrary have us fearing that this marriage just might happen. Combining these two automakers would be a messy job, as many models on both sides of the fence compete directly with on another in the marketplace. If the merger does happen, someone may have to sit down and decide which models stay and which go. We decided to play arm chair auto executive quarterback and hold a Battle Royale. We've pitted model against model in 12 segments in which GM and Chrysler compete directly. In this thought experiment, only one model in each segment will survive to see the New World Order.
