I just purchased my '08 QX and am completely in love w/it. I am a definite car enthusiast and there is simply no SUV that provides a better overall package of luxury and amenities in the world. It delivers powerful performance, it's very smooth and quiet on the road, the list of features is astounding, and it looks gorgeous. I test drove an Escalade. There is no comparison. The QX56 is smoother, quieter, has a lot more features, and actually provides better performance and quicker response than the Escalade.
Navigation system, backup camera, power liftgate, front parking sensors, intelligent key, voice commands, music box, bluetooth, intelligent cruise control, power third row, strong V8 engine, vehicle dynamic control, comfortable leather seating, First class legroom throughout, smooth & quiet ride.
Fuel economy is obviously not hybrid level, but it's what you'd expect from a massive SUV with a powerful V8 engine.
