@Brunton, I were you I would keep checking back on "My Tesla." Of course when I ordered online (with help of a Chicago sales rep on the phone with me), the sales rep said I would have to wait 7 days before it would confirm... and in that meantime I had opportunity to make configuration changes. However, when I checked "My Tesla" the day after submitting my order, the "Confirm" button was there... I pressed it... voila: I was in the production queue... no waiting 7 days.
