Hi, My name is Robert Smith. I live in the Black Hills of South Dakota. I just bought my first Cadillac. A used 2005 DeVille. What a sweet ride. I did not know how smooth the highway coud be. One question to this group. What is the function of the door from rear seat to trunk? I don't see how it can be used to get to trunk. Too small. Looking forward to reading posts. I will probably be a lurker.
