try and drive a GX at a dealer with the KDSS suspension. See if that makes a difference. Some 04's had it, and i think all 05's will. Good Luck
Sorry guys - I really agree with Robert - I have the KDSS and everything you can imagine on the 2004 GX470 - The steering is awful - keeps drifting either to the right or left - Its in the shop now and I have a loaner 04-RX330 (with nav etc) - It is a much better vehicle than the GX470 - with even more bells and whistles (head lamps - door illuminators etc ) - I am going to tradein the GX as soon as I find something comparable (with a third row seat) - There are rumors about a BMW coming out soon !
