Let's see. Foreign cars start costing 20% more, so why wouldn't American carmakers raise prices by 19% just to be cheaper and make more money. In other words, all prices go up (not necissarily by the same amount, but still up)
American cars are going to go up in price even without profit maximizing (which they’ll obviously also do). It’s a global supply chain. Infotainment screens and other parts aren’t made in America. Foreign manufacturers already produce cars in the U.S.
