I don't know what the difference is on why some 3800 series II have a dark grey engine cover, and why some have a black one. anybody know? With that, lets have a poll, who has a grey one, who has a black one? Mine is grey, and I'm going to buy a black one because I like the black a lot better. the part numbers are 24507933 for the black and 24507931 for the grey.
The 93 was black. However, the Lesabre of the same year was light gray. My Mother owns one. I'm betting the different GM divisions used different colors to make them look different. That could explain yours.
