I test drove a 2007 G35x that had the technology and nav packages and really liked the rear view camera. Did not test the cruise and it was during the day so did not get to see the adaptive headlights. If I get a 2008 the camera comes with the nav package so I'm decideing on whether or not I need the headlights and cruise. I'd appreciate comments from owners that have them.

Loved the car overall and one is on my must have list....

 

IMO the headlights are pretty gimmicky as they only move for the low beams, I honestly barely notice it. I like the ICC, it's nice to be able to use cruise control with out constantly adjusting my speed.
