I sent about a bunch of photos of my old car to my sales adviser and was given a trade-in estimate which was agreeable to me. I was then instructed and have completed the trade-in section of the My Tesla page. Roughly how long does it take for an official offer to be made there? What other steps will occur before a guaranteed offer is made? Will those steps need to be done before that section is marked as "completed"? Also, I have an option to request a final document review, but it seems odd to be presented with that when my task list is only 5 out of 6 complete. Thoughts and advice are appreciated.
