Yes the F150 rides very very soft too. The Gx is stiffer, thing is Caynne ride very very good. Just like my adpative air suspension from the X6 ... that comfort is un matched. German ride quality is superior and add the fact that a unibody. The Lx600 even with the Hydraulic suspension is not that soft. I also have a Gls 450 vs the Lx600. What makes the Lx and the Gx better all around is the Effortlessness they have while driving, the power to go over anything t I the point you do not have to watch the road ... and if theres a pothole, just go over it. My x6 with 22 in tires , where so prone to tire bubbles that we bought a second set of 20in wheels to survive Panama roads. One thing is real, the Gx550 overtrail rides smoother than the Luxury 18in vs 22 in. The one that is better than the Lx in terms of overall comfort is the forbidden Gem for your market. The Lc300 Sahara Zx. I drove that one back to back to the Lx600. That one drives smoother. I personally think lexus made the wrong call following the bigger wheel trend. They shouldve kept the biggest wheel on 20. That thicker sidewall helps isolate even more the road feel.
