Which Ford did you buy Marin? The F150? As you probably know I was in the car business and things really changed during the 25 years I was in it. I was with Ford, Acura and then GM.
I can tell you about when I saw changes with GM. Our Suburbans and Jimmy's (Tahoe) were made in Flint Michigan. The workers there were union and were openly fighting against management. They would clock in, take a break, go to the bathroom, eat, and maybe go to their station. The product was getting worse from there yearly and at the dealership level, we had to QC and fix the problems pre sale.
One suburban had a rattle in the door. They removed the door panel and inside that door was chicken bones and an empty liquor bottle.
The manufacturers had to start outsourcing. Van Nuys plant in CA was another. They built the F body cars. Firebirds and Camero's. They had to crush about 3 in a hundred because of problems that were unfixable and the workers wouldn't change. Finally GM said either do better or we'll close the plant. As you know, they sent that car line to Canada and the quality improved 1000%
It is a world economy now. I wouldn't be surprised if there wasn't at least 30% foreign content in your Ford. Which really doesn't matter.
