If you check the various other threads here on this particular car, especially in the marketplace, I think you’ll find that you can do better than what you are shooting for especially for this low of an MSRP.
What I am seeing is that only a few dealers have this car and only a couple sitting on the lot, so they are being aggressive marking up the msrp. This is the only one willing to keep at the MSRP and not even thinking about going any lower.
Unless you absolutely need a car immediately, you can save thousands by ordering from one of the sources in the marketplace or on your own as noted in various other threads.
The absolute easiest way to go about this might be for you to use a broker. There are a few in the marketplace that are offering pretty good discounts on an order and they can handle a lot of the details for you.
