I m trying to get out of my 08 LTZ for a 08 Z06 and can t seem to make the trade work at the dealer. I guess the used market is also hurt by the lack of new car sales. It has 5-6K miles and is mint. You can see I ve been here for a while too. Car was switched to Mobil One Synthetic oil. It is a lease .Interested persons can contact me best at e mail/ [email protected].
