I recently purchased a used 07 TL, the drivers side rear door panel is pretty beat up on the lower edge (looks like a dog chewed on it). Does anyone know if the lower piece of the door panel can be replaced without replacing the entire panel. Without completely disassembling it, it looks like the lower half is a separate piece.

 

Nope.. If you buy a new one they're around $200.. I repaired mine with a vinyl repair kit and re-'dyed' it to match.
