Picked up my ordered 2006 on Tuesday the 26th so I am not trying to give a detailed review yet, but some intial thoughts after the first week of owning it. I traded a 2004 SS with 9800 miles because I wanted the all new model. The '04 was a great car (no problems) and I sort of wondered if I would be sorry I did a trade. The new style I find more pleasing to me except I am a bit disappointed with the front end design (looks like a large smiling mouth to me). The rear end looks great, and the interior, although still looking less then impressive, is passable. I do have a slight squeak noise in the right front interior somewhere such as possible plastic trim rubbing together. My '04 had a similar noise.
Love the Bose radio speaker sound system. Finally they put SS in silver on the back and side so people know what you have (the black on a black car in '04 never showed up).
Did not receive book for Bose system with car- have called everyone trying to get the book (owners manual and CD mention it) and evryone seems a bit confused how to get one and from where. Chevy district people now trying. Liked DIC better up above then in the odometer area (but may get used to that
