You should mask and spray the gold roof/window trim black. It looks so out of place on the 1990 and up cars. I don't know why on earth Mercedes chose to use "gold" for those pieces when nothing else on the entire car is gold.
I changed out the one piece above the windshield, and the two long strips that run along the roof to hood line with the painted gray 86-89 trim. Pretty easy swap. Replacing the rear window trim is too much of a PITA, so I will probably mask/spray.
