I dont follow model Ys as close ( I have one, I just dont follow it super close) but there were points in model 3 production past where tesla offered the things that were mentioned (free paint upgrade / free wheel upgrade). Going from memory, I think it was likely a quarter in 2019.. perhaps the last one, but again I could be mis remembering it.
I doubt very seriously anything like that happens now, but of course anything is possible, I guess.
Reading through this thread, I see a lot of people speculating (hoping) that tesla will do X or Y because of current pricing, demand, etc. My own personal feeling is, Tesla will play hardball (they changed the order agreement to say 14 days instead of 30 I believe), and most people ordering in the past month or so will be pushed to take delivery this year or lose the $250 order fee.
People with trade ins, etc, should be moving NOW (its already too late for top dollar on used vehicle trade in), interest rates are going higher, and it remains to be seen how much of the credit the vehicle will qualify for (or whether tesla will raise pricing to capture it themselves... which they already basically have done).
All the people trying to delay are likely in for disappointment, though.
