Unless you are about to sell your recently purchased car right now, the "depreciation effects me" argument has zero weight. You wont realize any depreciation until you actually sell the car. If you were planning on keeping the car 4-5 years, the amount of depreciation AT THE TIME YOU SELL IT is what matters, not what it is during the journey until you sell. 4-5 years from now there might be a 10% difference but that difference might be in the hundreds of dollars because both cars will be worth less.
Its like people think the price they pay (or more) should be the only price anything is sold for, ever. I simply do not get that argument.
As for the "purchasers now pay less than I did" argument, I have absolutely zero sympathy for that one because its the same as every other car deal. For every other brand, your neighbor could buy the exact same car from the exact same dealer on the exact same day and pay 15-20% more than you, or 15-20% less than you, depending on your (and their) negotiation skills.
If you and one of your neighbors had the same house floorplan and you sold your home for 300,000 and 2 weeks later your neighbor sold theirs for 350,000, you certainly are not going to the buyers and asking for more money.
As has been pointed out many times, if tesla raised the price, and they came to you and said "oh I know you bought 2 weeks ago, but we need more money from you now" you would laugh in their face.
On the "my salesrep said", thats a joke, really. Who believes a car salesperson? In most cases, they lie to your face to make a deal because they work on commission. In tesla's case, tesla just keeps them in the dark. They typically know less than we do about upcoming things. Your salesperson almost certainly DID NOT KNOW. "someone" in tesla did, but certainly the people assisting with selling cars didnt.
Like someone else said, I was waiting for someone to start "complaining" about this, because it happens all the time here, and its ridiculous. People buy cars and someone else buys the same car and pays less all the time. it sucks for that person, but it happens. You just didnt know about it before when you bought other brands, because everyone was negotiating in "private" and lying about what they paid for the car online.
