I am the second owner of my X5. The first owner was an a middle aged female so I wouldn't think she beat on it. It was in decent shape all in all. I have had my X for 10,000 miles now. Sports mode and driven "hard" 1% of the time. 99% of the time nice easy driving.

I had a 2000 Expedition. I had a supercharger on it for about two years. That vehicle I drove hard. I went through 3 sets of brakes in 60,000 miles. No broblems with the front CV joints, driveline or transmission. It was putting out over 500hp. There is no reason the X5 transmissions should be failing at under 100,000 miles!!
