Yes, my SA is hard to reach sometimes, so I just called my local Tesla Store which directs to the general call center I believe to talk to someone. They require some sort of un-hold date, which I asked for January 31, 2022. You can always un-hold at any time through your account by clicking a button though, so I'd suggest to go out a little further and then have control of when to release. It took all but 5 minutes, as they had to put me on hold to request it and then I logged out and back into my account - then Bam, it's done. Only sad part, is you may or may not be at the back of the line when you come off hold, BUT you do keep the price of your OG order as long as no changes to the vehicle. It's likely Tesla will change prices again, of course not certain.
If people are waiting an extra couple weeks or month strictly for the EV rebate (pending if makes the final cut), then hopefully they are strategic enough to make a couple simple tax changes to take advantage of the $7500 back. Plus they would have all year to do so before filing in 2023. Couple thoughts on the supply/demand of Tesla coming into 2022 in my opinion: Austin Factory will be ramping up into Q1 2022 making wait times likely drastically reduce as the year goes on. Less wait times = people may not be urged to buy overpriced used cars, driving those prices down. In addition, if the EV credit does pass, and even if Tesla slightly increases costs, people likely still won't have to wait as long with factories running and they will get money back - driving used car prices down. Personally why I wouldn't want to play the shuffle game of buying a 2021 and then a 2022 trying to make money back or break even. I can wait a month or two and save the maybe.
