I bought a off lease 09 X5 D after my wife's new explorer was hit and totaled.
After only a few days all i can say is wow! 425 pound ft of torque and 28 mpg on the highway is an incredible combination.
The X5 has amazing handling and great brakes.
We have owned a fx 35, a xc 90 and a ford explorer and this X5 is by far the best SUV we have owned.
This engine is perfect for a 5000 lb truck. It pulls effortlessly and for such a heavy vehicle it has great pick up.
If you are looking for the perfect combo of fuel mileage, power, comfort and handling look no further. I highly recommend
