That really does suck
@EVMiami ; at first I was reading it, like others I'm sure, thinking boo-hoo, he only got the $7500 discount (we took delivery of our latest Y earlier in December, so only got the $3750), but then they totally screwed you buy pushing your date into the very narrow window where no discount exists, and the price reduction hadn't yet taken effect. Getting hold of an actual person in Tesla, who actually cares, is really difficult these days, it's one of their main weaknesses. At least at a traditional dealer you can speak with the 'manager', and they'll normally throw something in to make you go away. Tesla hides behind their app.
The best and worst time to buy a Tesla is the day you buy a Tesla, I think we all know that's a fact of life. All the owners of cars being sold this month will probably be pissed when HW4 is announced (I still don't think there's even a remote change they'll attain Level 4/5 with HW3). But mentally (this is our 8th Tesla I think), I just get past it now. Nearly all of the Tesla's I've bought have been significantly upgraded within weeks or months of purchase, and in the earlier days of Model S, significant price reductions.
I'd still continue to try to reach someone useful at Tesla if I were in your shoes, but also try not to let it eat away at you, and enjoy the car for what it is.
