Imho the X-REAS is worth it. I can without a doubt say that I have driven and am driving both 4runners with and without it. The difference is like night and day. Some may not notice the difference, but I do. When I drive my SR5 (when the wifey isn't using it) it handles great for what it is onroad. However, when I drive my Sport (wife no touchie at all - hands off), it is so much smoother. It doesn't dive as much in hard braking and cuts into corners smoothly without excessive roll. If you really want it, get it. It also comes with the air suspension on the Limiteds. You don't want to buy something that doesn't have a feature you want. You won't be happy and you'll end up saying "shoulda" everyday as you drive your X-reas-less truck. Besides, your getting a Limited, be a crime if it didn't have X-REAS. Life is too short, man. Just my two cents.
