After having the car for a month and a half, I have now found through the local dealer that the color of my old girl is Z9U Volcano Black Mica. I was sure that it was a deep gray color but it seemed a different color in different levels of light. I think that it is a great color and have seen what it looks like cleaned and buffed - awesome! Maybe with some hard work and a beer or two, I can get mine to look a lot better.
