For what it is worth, I see a resurgent US auto industry, if this is possible, with a merger of Chrysler and GM.
Chevrolet: Cruz, Malibu, Astra, Corsa, Caravan.
Cadillac: Luxury stuff.
GMC: Trucks, SUVs.
Jeep: Wrangler.
Any way you look at the equation, there are going to be many, many plants close, at least thirty in North America.
