RR Sport sure looks great. The interior is very nice and (along with the new Cayenne's interior) make the X5 look quite spartan. Having said that, I think the BMW tech, ride, and performance are superior. Reliability has also been disastrous for the Range Rovers. I just don't trust them. Several friends have had nightmare stories including electrical problems, mechanical problems, and even leaks.
