Purchasing bmw x5

Im 25 looking to buy a bmw x5 the car cost 50 I have 20 down I’ve never finessed a car and I’ve been driving a 2007 grand Cherokee since I was 18 . I really like the sporty and luxury look of this car. However my dads telling me about the Maintenance and parts cost on a BMW would be really expensive keep in mind he has a Mercedes so idk how much different a bmw would be. So I’m here asking people who actually own and drive these cars what they’re experience is like with cost of ownership . The car is a 2023 bmw xdrive40i awd with 11k miles.
