Is it possible to order specific interior leather color? For example, I want to get burn orange leather with Pikes Peak White. Obviously, this isn't one of the avail color combo. I know when I ordered my other vehicle, you can actually specify a specific color even though it's not on the "approved list."

 

No, you can't. But some have put in aftermarket custom leather seats. See here:

Note: You can't have side/curtain airbags with aftermarket seats.
