Types of door panels
John Green writes:
Mercedes door trims can be divided into two specific groups. Those that you pull up to get off and those that you pull out to get off. And then of course there is always an exception to the rule.
The following are of the pull out style where you need to very carefully undo each clip with a trim tool.
W120, W121, W180, W105, W110, W111, W112, W108, W109, W114, W115.
The in-between one is the W123 where you need to undo the trim clips on the door trim and then pull it up.
All the others are the pull up style, where they are pulled up after undoing all the bits that hold them on.
W116, W126, W201, W124, W202, W210, W140, etc, etc, etc.
