I disagree, production in Mexico in many instances would make vehicles more expensive, for example the #1 most American car per cars.com is also the cheapest car to own in America based on all costs of ownership. Sourcing out your manufacturing to multiple different places adds to the cost of a vehicle.
I don’t need to “look into it” I’m in college everyone knows what economies of scale are. It doesn’t matter how you google because IT IS CHEAPER TO MANUFACTURE CARS IN MEXICO. There might be exceptions to outsourcing but they don’t apply here because it is simply a fact that it’s cheaper
