If anyone could please give me some insight to the taking care of carbon black on your M5's. It would be of great help. I have had many silver cars in the past and I am just about done with that choice. I have had ti silver, sebring silver and gun metal gray metalic. I really like this (M color) Carbon black, however not sure how hard it is to take care of. Is the clear coat easy to mark up when drying? (ie scratch marks from washing then drying over time.) How does it look in the day light as well as under lights at night? I welcome all comments good and bad. But please only comment if you have this paint color. Thank you very much. Dave S.
