I just bought a 2006 Cadillac CTS and Im not sure if mine is a special package or exactly what I have. My paint is Thunder Gray, I was told that was an upgrade option when the car originally came out. Like people actually paid more for this color. I have the 2-tone leather seats in the front. The steering wheel has wood on it and so does the door handles and the dash board where the cd player is. Its a 3.6l V6. I do have onstar and xm radio. Do I have anything special or is it a base model? Please someone help me out here...
