I too ordered the Sly. It's an interesting, and (in my opinion) beautiful, color. It looks slightly darker in low light, and a lighter in bright, direct light. There's a CTS in the parking lot where I work, and depending on whether or not the owner parks under the cover or not, the paint takes on a different appearance. The brochures and pictures make it look slightly darker than it looks in the bright sun.
The color, when I see it, is a calm, understated, yet striking silver-grey with a subtle semi-metallic glisten. I saw the two tone interior with the Sly at the LA Auto Show in Jan 2005, and it was well balanced. It has a refined appearance.
My thoughts are with you for a safe return. Thanks for your service.
Be well.
