1) Are you trying to gang three companies up against one, top-poster? 2) As usual, you are wrong. It's much more complex than that. For example, GM has a much broader range of products than does Toyota. This means their product is "just right" for more people. This is a separate issue from "value, care, and quality". Also, it's a well-known fact that millions of Americans will only buy American, irrespective of of which manufacturer offers the best "value, care, and quality" package.
Don't you tire of being wrong, troll?
