I would try to avoid the dealers and put up adds in the Daily Oklahoman, Ebay, and Craigslist as well as go to this area of the forums:
and post that you have this car available. A lot of people are waiting 2-4 months around here for a Camaro. Dealers in the OKC area will only sell at MSRP if someone orders a car and is willing to wait the 2-4months. If they have them on their lot, they are selling for 2-6k over MSRP. You can go to chevy.com and build your Camaro to find out the MSRP.
