Looking for X5 - NEED Advice - Reliabilty ?

[Woolf5150]

New here and need advice. I am looking @ 08 and 09 X5's. I pretty much know what I want but i am a little concerned about the reliability of these great looking SAV's. I have scoured these posts and have read the issues that people have. I am seeing the money it takes to keep them fixed and running and this makes me nervous. I always thought BMW were reliable machines but I am unsure now. Maybe I am over analyzing all of the information but I need a SAV that is reliable and does not need much more than regular maintenance. I have always had US made cars. Outside of tires breaks etc i never worried about the electronics, electronic water pumps etc that go out or leaks that are expensive to repair. SO please reply back and let me know what my real expectations need to be when I am looking at these machines. Also, should i favor an 09 over the 08's?

TY IN ADVANCE FOR ALL OF YOUR HELP!!
