What leads you to this statement? The QX is built on the Nissan Patrol, which is a very capable 4x4 used in other parts of the world.
You can't compare a QX to an LC. Completely different vehicles. You can compare the QX to Lincoln, Cadillac as they are 1st one road and off-road being secondary. This group is more off-road 1st and on-road secondary-LC,G550,LR4, Range Rover and jeep. You will never see an Infinit trying to follow the LC off-road. When you mean it has more technology, are referring to the interior Bells and whistles? Because, no way does it have better off-road tech, and personally you don't want so much tech to go wrong while you're in the boondocks. To me, the least amount of "tech" the better for longevity and reliability. The big Infinti is for housewives and not anyone over 6ft. Very small cockpit!
