Cause Americans Car companies are all about making cars for cheap, and selling em at relatively reasonable prices no matter what their reputation is. The more the sell, the bigger they get, and the bigger they get, the more people think, "Oh Gee, they're the biggest car maker in the world...many people must like them...I guess I'll buy one too."
Foreign Cars rock, because they're all about quality, and satisfying the driver...well not the late, and hugely unloved, '90 Pontiac LeMans, aka Kimchee Burner.
