One thing for certain and that is, they aren't made in Milwaukee, Wisconsin today as the factory is closed except for engineering. No production there and hasn't been for years. I believe high labor cost and suffocating union rule cause them to close up shop there.
Sadly, I see the same fate for domestic automakers still based in greater Detroit. With a looming UAW strike and what I consider insane demands, what is left of the not so big 3 will be moving out to greener pastures.
Auto makers are in a bad spot today. Lower profits, higher materials costs, insane union demands and a weak market will drive the move.
