Interesting times... seems the demo buys may free up some spots for those of us waiting on their new deliveries. Some of us rushing to buy the "older" cars with passenger lumbar support and radar (though it will likely not be used by Autopilot in the near future), while others don't want to miss out on other updates to the car (door trim, headlights). Some want to buy before next price hikes, others want to delay for possible EV tax rebates, that may or may not pass and may or may not be retroactive to May 26th.
It's all a guessing game.
Good luck to all! At this point, I *think* I'm good with waiting. Sure, I'd rather have radar, but it may not matter. :-/
