Ed, I know what you are saying. But sometimes the “worker bees” just get the work done and upper management may not know the details. Been there, done that.
Now obviously I have no personal first hand knowledge of this for Camaro production, but for minor things, I sure would not be surprised if it happened. Not all day, every day, but occasionally. That’s what inspections are for (P T B). Again most of these things were fixed before leaving the assembly plant.
