First, establish a relationship with a salesperson you trust at a trustworthy dealer. I don't know about New York, but I can recommend one here it Texas and BeckyD at Rogers gets lots of kudos here on the forums. She's in Woodhaven Michigan.

You should send her a private message to contact her and she can let you know what kind of deals are available on which cars. There are plenty of Camaros with deals available.
Let the salesperson know what you want and what you are willing to pay. It can take time. Also, you should be willing to fly to a location and pick up the car for the right deal. Or the car can be delivered. Air fare will be a fraction of what you can save with the right deal. In the last 2 weeks, I purchased 2 vehicles, the Camaro and an Equinox LTZ. I saved over $15K on the 2 cars (over MSRP) here in Texas. The deals are out there.
