I don't get it either. I literally had to replace the cat on my car after it started throwing a check engine light. I took the old one to a scrap yard, and the amount of info they asked me for was crazy. They wanted the VIN of the car, all of the car information like make, model, color, etc, then photocopied my ID and kept records of it. This is in Washington, so it may vary by state. You'd think this would be enough, but there's someone who is not asking questions... So many scrap yards are out of business in our area now too, I don't get where people are taking them to. Maybe people are taking them out of state to where people don't ask questions.
