I just purchased a '22 X3 xdrive 30i. We're having fun with this one and now I think I want a second X3, but would like a 6 cyl. I want an xdrive, but should I get a 35i or the M40i. I understand the M40i didn't become a mild hybrid until after 2022. Correct me if I'm wrong. Any engine reliability issues with either one? Thank you
