I don't have it yet, still deciding on colors. Light colors will not show spider webs or hairline scratches as bad as dark colors. In addition, dust is not as noticeable from far. I wash my car all the time and would use a chamois if it was a dark color. However, if someone else wash your car and used a towel, would it cause swirl marks on a metallic dark color paint? I have a silver Mercedes and it is easy to clean. I was debating if I should get an IS in granite.
