I placed my order for an AWD on 5/20. I want to change my color selection from MCRed to Obsidian Black so I called tesla sales, was informed that changing the color would delay my reservation - "your current estimate is 2-4months, it will go to 3-5months if you make any changes at this point" - got the same answer when asked about adding FSD. Not sure why it would cause a delay assuming they haven't started making my car yet (I still have the 'Edit design' link in my account). Did anyone try to do this and did it affect your delivery timeline? As previously mentioned by others, I think the answer you get depends on which agent you get on the phone and so I hope it doesn't delay my delivery.
