I don't think many people are changing out their transfer cases or differentials. And if you're referring to the fluid that's not being done either as bmw states the fluids are "lifetime" so there is no maintenance for them. I would say the lower the mileage the better. In my experience with the car so far it seems the weak points are all in the suspension. I have 60k on mine and have some bearings that need replacing. My front EDC struts had to replaced under warranty at about 45k and it appears the rears now need to be done. The engine so far seems to be up to the task so I wouldn't worry about that.

Just understand the cost of owning a bmw is naturally going to be higher than say a Kia or Honda. And when it comes to insurance don't ever, EVER, buy a car you can't afford comp/collision with a $500 deductible. If you can't afford the proper insurance, you can't afford the car. Simple as that.
