We ordered our M3 LR AWD non-P on July 13, 2018 and have an estimated Sept-Nov delivery. Still no VIN assisgned yet, and we expect we're fairly low on the list, given that current owners are no longer given preference. Yesterday, (Saturday), we saw a M3 Performance with the White interior and just loved the look, so we decided to change our order, now that the white seats are available for the AWD non-P (wasn't available at the time we ordered a few weeks ago. We have not had the edit button since shortly after confirming our order, and on Saturday, the Tesla guys were not able to make that change either - and they were not sure why, since they confirmed that I have not yet been assigned a VIN. My questions: Did anyone change their AWD to white seats? Did you have the Edit Button still or did you have Tesla do it? Did the change cost anything (above the extra 1500)? Did the change impact your estimated delivery? Thanks!
