I love black cars... My X is Super Black and my Probe was black...
What I did to keep my Probe looking like new was buy a bottle of duplicolor wax. You use it hust like any other wax (I used it a bit more sparingly), but it's the color of your car. It hides pesky scratches and swirls for much longer than any other wax I've used (talking months). Made it look like fresh paint. Only thing is that your hands and towel turn black, but that washes off (you hands)
