Once you get your production number from your dealer, you will be able to see it on owner's circle... but beware that it may not be your spec at first... they fill it up with a dummy order to hold slots and they modify it to your spec... you'll see it reflected a day or two later. Mine is also slated for mid January (ordered 3 days ago).
