I have a white diamond pearl 04 TL. The bumper doesn't match the side panel between the back door and the back bumper. The panel below the doors from wheel to wheel don't match the other two, for at least 3 variations in color. I have seen at least two other 04 TL's in my area that are exactly the same. The new 05 white RL I just saw does not have these variations. What gives?
