You know...I didn't get the charcoal because I've already got a black car, but I was feeling the red jewel tint. It stays clean longer than a day very nicely. The black interior...well, I find myself vacuuming out the interior at least once a week.Tom H said:My favorites are Red Jewell, carbon black, Deep Blue then gold mist..in that order. However when I buy it will be Gold Mist/Tan interior. As beautiful as dark cars are when are clean they only look good for about one day after a wash/wax job. They amplify every minor surface scratch as well. I prefer the cleaner look and easier maintenance of a white, gold or silver car.
