Reliability and Durability of the BMW X5: Pros

It appears from others to be a safe and reliable car. If the engine holds up as well as my other I should have it a long time. It has 60,000 mile but looks and drives like new.

Got in mechanical trouble all the time~~~

The worst car I have ever owned. The transmission failed 4 days after the warranty was over - and the vehicle had less than 45,000 miles on it then.
