I used to work in a plant that made parts for both Dodge and Toyota. The Dodge parts were flimsy and were even allowed to leave the factory with flack (small slivers of plastic leftover after the molding process) attached.

But the Toyota parts were a whole other ballgame. Sturdy, dashboard components filled with reinforcing material, ect. A rep from the company even came freq. to inspect the facility and process too. We were even asked to give more attention to those components.

I think it's the whole "honor" thing in Japan that keeps companies there honest.
