I too have a black Crossfire. I wax it often using Meguiar's cleaner wax and Turtle Wax Ultimate Gloss (or is it Ultimate Shine?). In between waxing, I use The Glosser (soft disposable cloth impregnated with wax). I am careful when I wash and wax the car, but one thing I HATE is that minor scratches and imperfections really show up on an all-black car. I even noticed a few of the minor swirls, etc the day I bought it brand new. Take it out for a couple of hours, and a fine layer of dust finds its way on to the body. After washing, it has to be dried to perfection as well, since just the tiniest of water droplets becomes a water spot visible from ten feet away. I love the way the car looks when it is clean, but owning a black car is a constant uphill battle!
