I worked on the Lexus line in Georgetown, KY one summer between semesters. Their standards are insane. Worked the Toyota Camry line the summer before that.

On the Cry line, if they found a defecy, they would correct it, then have a QC stand there and inspect every affected car for the next month.

I stood on the line with a screwdriver to check the tightness of a single screw on every sunroof in Camrys. It was so heavily coriographed, it was like a dance.
