Traded a 2001 Sequoia for the GX. Need something to tow a 5200 boat & trailer, and the GX470 does the job with ease. This vehicle might be pretty, but it's a real truck. Even though the Toyo and Lexus both have the same 4.7 liter V-8, the horsepower and torque upgrade in 2005 is very noticeable. It pulls like a beast. Love the backup camera, I can put the hitch ball right under the trailer coupler without looking over my shoulder.
NAV, 14 speaker stereo, ride adjustment control, auto height regulator, rear camera, great feature. Haven't really checked the mileage, but on board computer shows 21+ at 70 MPH. Love that!
More console and storage room. Lose the 3rd seat, can hardly seat a teddy bear in those things. Allow NAV adjustment while driving.
