There was a time when buying American was a clear-cut thing. March into a GM, Ford or Chrysler dealer, drive out with something. It's not so clear-cut anymore.

Cadillac's Catera is designed and built in Germany. Chrysler is owned by the Germans. Hondas are designed and built in the United States. Many buyers might hesitate to purchase an Asian or European car. American manufacturers are building some of the best cars in the world.
