It is a little tricky and very easy to damage it.
Removing trunk emblems on 1973 to 1985 Mercedes can be hazardous to the emblem and the paint on the trunk. You must excercise extreme caution. Don't ask me how I know this...
Problem & Solution
Common among these chassis:
R107
W114
W115
W116
W123
W126
The emblems during this period are held on with multiple pins fitting tightly into plasic gromments inserted into holes in the deck lid. Kent has seen so many damaged emblems that he decided to do a detailed on demand video on how to do this properly. It seems like it should be easy, and it probably is if you don't care about damaging the car.... :-)
