I placed an MXP order a few weeks ago.
The expected delivery date went from February to March and then became TBD.
When I placed the order, on the order details page, the car had red brake calipers (Yes, I know these are just red plastic covers.)
Yesterday, I suddenly found that the red calipers in the screenshot of my order page were gone.
I thought I was misremembering, and maybe the red calipers never appeared in this picture. But then I remembered that I received a "Confirming your Model X update" email from Tesla not long ago, and I realized something fishy might have happened.
So I checked the URL of the image in the order detail page, it's something like
This URL format means that there is a connection between the picture and the car's configuration. You get different pictures with different option codes.
Then I checked the 2 emails I received from Tesla:
Now I realize that the disappearance of the red calipers was not a hallucination on my part. They did modified my order. Then I digged into the option codes in the email:
The only difference is that the left has WX01 and the right has WX00
Google shows that WX00 means 20" Cyberstream Wheels and WX01 is unknown.
Tesla would not send me an Email just to modify a picture, so the only reasonable explanation is that when I ordered the car, my option code was from new production cars. Then they found a previously produced car from the inventory and wanted to assign it to me.
I don't want to accuse Tesla of doing it wrong because the cars in inventory are also new (if it's true that they never reassign someone else's rejection). My point of this post is that if you recently ordered a Model X and you want a new factory car instead of an inventory car, pay extra attention to your order. At this moment, the difference is huge, new production cars are likely to be equipped with HW4 and upgraded cameras, and inventory is likely to be only HW3 and not upgradable to HW4.
