Hi, I apologize if there is a thread already like this. If one exists, please direct me to it. I'm days away from taking delivery of my 09 CTS awd with PDQ package. I'm wondering if there are key questions I should ask and things I should look for when inspecting the car and before I drive away. I realize I can always come back or call, but I'd like to have things as close to right as possible before I depart.
