The SA's know absolutely nothing. One told a guy above he wasn't getting until december! Use your own judgment but from someone who ordered in Feb and am seeing april orders with vins, same build but with 21s its getting old. I don't have months to wait and sure as hell not going through this process again when back in the country.
Ive counted 14 people that have posted on this website not just this thread that have switched and received dates. Not to mention those who don't even know this website exists. The website itself (teslas) shows quicker delivery for 21s than 19s. It's not an EOQ push, or it would be cars going to FSD purchasers. Tesla uses credits from other auto manufacturers to push back into R&D which is what FSD would make a substantial part of as FSD is nearly all profit compared to the 21's. If this process has taught me anything SA's know nothing. Not really sure how thats debatable at this point.
