I have a fully loaded Granite Black 08 LTZ v4/6speed. I also had the dealer put on the 18" LTZ wheels that come with the v6 model. This car only has 3000 miles on it. I am looking for anyone who has a black LTZ v6 who may be interested in trading me for my v4. My car runs great, but I am having regrets about not getting a v6. I have already tried my dealer, but I would be taking too much of a loss. Anyone interested?
