Should I buy X5?

basically, I drove a friend’s X5 back in 2020 an it has been on my mind since. I want to change my RAV4 and X5 is my #1 candidate without researching others. thinking used 2020-2022 sDrive40.

am I gonna be in the world of pain from the maintenance standpoint compared to my rav4 that never asks me for anything? I understand that maintenance cost will be higher but my concern is whether some known issues might brick my car and cost me a fortune to fix.

in the same context, is buying a CPO vehicle worth the additional money?
