I bought my P100D Ludicrous when they were priced much more expensively in 2017. I like my car. I would NOT go back in time because I needed the car when I bought it. I think I will be keeping it until 2025. By then it will have paid for itself.
Make a decision, accept it, and don't look back. No regrets. That's how you live life. You need something, you deal with it, and you don't torture yourself by rethinking and re-guessing your decisions over and over. Just learn from prior mistakes.
If you don't need the car now, then wait. If prices go down, great. If they come back up, cest la vie. If you can't wait, buy now, and then stop looking at prices because that won't change the fact that you paid what you paid when you paid it.
No one here is clairvoyant, AFAIK. If so, they sold their stock, bought bonds, stocked up on groceries, and is/are living on an island where they will not need a car.
