Hmmmmm

It gets complicated when the vehicle's parts are from all over the planet. I just have this feeling that when you buy a vehicle with a foreign made sticker (label) the money from the purchase will still go back to that country.
Manufacturers sub their work frequently. The parts go out for bid and usually the lowest bidder receives the contract to make the parts. Sears is a good example. Sears does not make their own power tools.
Bottom line? It would take someone more savvy then me to explain the economic impact. While the parts made in the USA will keep some Americans working, which is good, the real money will still do to a foreign country.
