@cWatkin Yes, I believe both the Fiesta and the Focus are built in Mexico. The Hermosillo plant in Northern Mexico is one of Ford’s best plants. Dont worry about the quality from there.
Since Canada, Mexico and the USA have Free Trade, the compnaies can swith plants easily as manufacturing location. When Ford built Escorts in the US they lost $1400 on each car under the old union agreements.
GM with their new labor agreement is now able to build small cars in the US, Lordstown, Ohio, for instance with out going broke.
For years your conservative US friends bought cars believed to built in the US. Many were actaully built in canada, since Canada for many years produced 3 million vehicles but the local market only took 1.2 million.
