Personally, I think you should wait. A car in your configuration and color will pop up soon enough. I was in the same situation just two weeks ago. They told me there wasn't a car within a thousand miles with my color and configuration, but a couple days ago they were able to locate the exact car I wanted.
My philosophy is, you're spending this much money, so you need to get what you really want. You don't want to leave anything to the "what ifs?" and "I wish I had waited." I've rushed my decision on cars before, and although I was happy in the beginning, after the novelty wore off, I wished that I'd just held off a little longer. Just hold off a bit more if you can, it'll be worth it.
The worst thing that can happen if you wait is that you'll have a little more money in your pocket when it comes time to purchase
