Ford makes more than one car. Shocking news I'm sure. If Ford wants to belly up in the US and move out entirely fuckem. The loss in sales would far outweigh any profit gained by moving entirely and pissing off at least half if not more of the American consumer.
Ford wants to build their loss-lead cars in Mexico. Ford makes little or no profit and the dealers make little, but can pack financing and dealer added crap to the price.
The real profit makers are the big SUV's and trucks which are all made in the US. For instance the profit pack on a 2017 F-450 Premium is $30K. Now when you buy one you know where to start the negotiation.
Realistically, longevity and commercial use, Ford (minus blue-tech) is your only choice for American built. GM is crap, and Dodge, Chrysler, RAM are what crap aspires to be. Light truck, Ford hands down.
