Mercedes and BMW have many different "models" for a similar body style. They classify each car individually, all that could be different is the displacement of the engine. i.e - The c-class Mercedes. There are 4 different models of the same car! different engine, different equipment, same frame same body. I bet if you add it up, there are probably 80 different "models" of the Ford f-150. Heck, using that logic, there are 5 crossfire models, not one the way chrysler uses it. It all on how you define the word "model".
