My wife drives a Lexus RX330. I drive the X5. On long road trips on Intersate Highways there is something to be said for the Lexus ride. From my albeit brief encounter in the E70 I did get the feeling that their was indeed emphasis on a smoother ride. When I mentioned it to the BMW salesman he said not to let that fool you as he drove last week the E70 as well as the RX350 at the Performance Center and said the BMW edge is still very much there in manuevers. I think the new suspension is going to be welcomed by most.
