I just thought of something else. My car, when it rolled out of Saint Louis, got the wrong door on it, because it has a different VIN sticker on it. How do I know that it's the wrong one? Because my father-in-law was the original owner, and he never did anything to alter the car. My VIN is 1Z8749S418330, an L-82 (which is the correct VIN). The door sticker VIN reads 1Z8789S418303, an L-48. Another tipoff that this was GM's mistake is that it would be one heck of a coincidence for me to get a used door with a VIN that was 27 cars ahead of mine. So, if anyone knows whether or not 1Z8789S418303 is still on the road, let me know. I'd love to see if he has my VIN tag on his/her door.
