Have you asked your dealer? I would imagine it depends on them, and chances are they won't want to turn away more profit. I know a friend was able to add a bunch of stuff when he bought his '06 a few years ago.
Also if you fill out that you are interested they will mail you a brochure, there is a chance it will have a 750 off coupon in it.
+1 on this. I have been filling out their surveys at cars shows the last couple of years. I got one of those brochures about a month before buying my '13. I forgot I had the rebate card at the dealer--but I now have the $750 sitting waiting for me to decide what mods to spend it on.
