I have question concern about the color code#, I'm driving a black 1990 M3 E30 and I want to change it to gray color, I tried to contact BMW but they didn't take any response. I really want to have the original BMW gray color, easy to take care of. Does anyone can give me a gray color code#? I'm in Thailand...they have Standox, Dupont, Parrot. Thank you very much....appreciate it.
