I can't speak about the cheaper materials bit but that's simply not true. Major manufacturers move their productions to China/India etc due to reduced labour costs but they still specify what quality control measures are in place as well as their manufacturing tolerances. I know not a car but still applicable, all Giant Bicycles are manufactured in Taiwan. Despite this, they have sponsored (ie - their bikes are ridden by) 3 international teams and a number of national teams. It's not about where it is made, it is about how it is made, what it is made from and what their tolerances are.
