I bought my Model 3 LR RWD (with EAP) in December '18, so I've had it for just over 3 months. I paid roughly $7,200 more than if I bought the same car today. In fact, I could buy a LR AWD for around the same price as I paid for my LD RWD 3 months ago. But, it is what it is. At the time I bought the car I was OK with the price, and nothing has changed with the car itself. I still love the car, I still love driving the car, and I don't regret buying the car. I can choose to be pissed off that the price of my car dropped 10%, or I can just enjoy the car I bought and not get worked up about the fact that someone who buys the car today might pay less than I did.
Am I "happy" that the price dropped? No, not really. Could I use that $7200 for something else? Definitely. Am I "mad" that the price dropped? No, because prices change all the time, but most of the time we don't know about it.
I understand why some people are upset, but to be honest, when was the last time you bought a car and then paid attention to price changes from the manufacturer afterwards? If you buy a 2019 Volvo today, and then two weeks from now Volvo has a red tag sale where the price of your car drops by $5,000 due to dealer and factory incentives, would you even know? If you went to the Volvo dealership and complained, what do you realistically think they would say or do? Odds are, you wouldn't get your money back... The reason we even know about the price drops is because we are Tesla enthusiasts and we pay attention to Tesla news, but that doesn't mean that we should expect refunds or compensation because the prices were lowered, even if they were lowered by a noticeable amount.
The price drop is what it is. The argument about Tesla saying that everyone pays the same price for the same car without discounts doesn't mean that Tesla will always sell the same car for the same price forever. If you buy a Model 3 today, you will pay the same price as every other person who buys the same car today, and tomorrow, and next week, and probably next month. In 6 months, probably not. In 1 year, doubtful. The prices will always drop over time, even if the car itself has not changed substantially, because that isn't the model that Tesla follows. They don't do "model years", they just build cars and then update them over the air. Someone who bought a Model 3 a year ago likely paid more than someone who bought 6 months ago, and that person likely paid more than someone who bought 3 months ago, but we all have the same car with the same features, even if the cars didn't all have the same features at the time we bought them.
