The American entry into this profitable market segment is? Zilch, nada.
One reason is they simply don't build any vehicles in that profitable range of the market, or in many segments, period.
When Toyota introduced Lexus, Nissan introduced Infiniti, Honda introduced Acura, American companies did nothing.
At the other end, when Toyota introduced Prius and then Scion, they did nothing.
GM, Ford and Chrysler are Hq. in Detroit--the dying city. They ought to get out.
