Why? Closing this plant doesn’t affect Saturn in any way.
Also, California would have to totally change much of their labor code to get rid of their mandated unionization. Pretty much anyone opening an auto plant in CA *has* to have the UAW there. Good luck with that idea when they can’t even agree on how to balance the budget.
Penske bought Saturn, and he’s looking for places to manufacture them. He is already in talks with foreigners, and looking at some locations in the South East.
