Is Porsche for me?

Hi there. I'm a BMW driver and recently my 2018 X3 has become a money pit with repairs. I've maintained it meticulously through only dealership services. I just hit 90k miles on it but the constant costly repairs started at around 70k. I want something reliable with some luxury. But I don't want to have to sink $20k+ a year into repairs. While I realize Porsche is a much more expensive upgrade than BMW, I'm wonder what everyone's experiences are with your Porsche. Does maintaining a Porsche cost around the same or more? I'm disappointed in BMW. I expected to have it for at least 150k before every little part needed to be replaced.
