Although when considering the original theory, it should be noted that the US's global manufacturing leadership in cars collapsed. It moved form the States in 1950 to Asia - first Japan, then China. If the US consumers having cheap cars was a goal (which, implicitly, is what those 3 dot points support) it would seem that US policies were ineffective. If anything, car prices depend on labour costs and the dealership structure is a sideshow.
