Didn't know there is only a certain number of vehicles they are going to produce.
And the first three years of production of that certain number of New Ford GTs were assigned to the owners almost two years ago. Your only hope of getting one will be to try for the application process for the last year of production which will happen some time in 2019. Stick with the 05-06. They are not built out of unobtainium.
However, as mentioned in your other post, if you add other colors to your selection criteria you will certainly find many more opportunities. You can chase a black or yellow car for a long time and pass up multiple "for sure, sign on the dotted line and it will be at your house tomorrow" red cars. (This is not limited to red, but there are more reds than any other color, and pointers to several reds in your price range have been posted). If price is your limiting factor, color should be a second choice or you'll wait and wait and as Kayvan said, the bar will just keep getting higher and may be moving at a rate that makes closing the gap more and more difficult every day.
That said, what you want might just show up tomorrow, who knows, but the odds are not in your favor.
Good luck with your search.
