Just wanted to share. I edited my preorder from rwd to awd and I kept my original order/reservation number. I tried searching and couldn’t find a definitive answer as to whether you’re kicked to the back of the “line” when changing your order. Some people from the model 3 preorders reported a changed reservation number. I still may be moved to the back of the line but I figure this was at least a good sign to keep the same reservation number. Just wanted to share in case any else wants to edit their order and is hesitant to do it. I say just get the car you want and don’t compromise.
