Car is great. I have everything except Navigation package. X5 drove great for the first 5200 miles until the electrical system and comfort access failed. Been without my ride I've had for 5 months for two weeks now. This is my first BMW, and may be my last, since the X5 is proving to be unreliable.
Get up and go, handling (love the sport suspension compared to the base), the upgrade seats (very comfortable).
Vehicle needs to be reliable. The service department for BMW needs to show confidence in repairing problems instead of shaking their heads saying they're "looking at it." Try replacing the bad parts!
