LX470 definately if money was no object. I got a chance to drive it at a Lexus ride and drive and I'm impressed (the GX handled just as well, if not better because of it's smaller size), way better off road manners than the X5, ML, Escalade, Range Rover... what a shame, the Navigator was there the year before (2003) but not in 2004 due to off road capabilities, 2005 just had a cheezy metal ramp, thick cords/ropes and rubber rings. 2003-04 had a dirt trail, big mud hill, rutted trail for suspension travel/articulation. The Navigator was directed to go around mud hill.
I wouldn't consider the GX, CRV or RAV4 for sole reason of it having a barn door on the back. What's worst of all, the mentioned doors are hinged on the wrong side, unless you're parked on the left side of a one way street. If the GX did not have that barn door, it'd be a very appealing SUV. The KDSS is very nice though.
I like the extra amenities in the GX, but most major features are present on the 4R as well, navi, bluetooth, memory seats (no mirrors on the 4R), backup cam, dual zone climate. What one gains in one area is missing in another, i.e. aux input on the 4R, Mark Levinson on the GX, roll down rear glass on the 4R, auto up/down windows on 4 doors on the GX, etc.
Too bad Lexus hasn't incorporated Smart Acess in their SUV line up. Even the Prius and Avalon has it, if the 4R has it, it'd be a perfect vehicle. Also, someone mentioned the remote on key (Lexus style) on the RAV4, the Scion tC has it as well.
