we too were looking at x5, when the wifey decided the x6 looked better (who am I to argue?? hahaha!). could NOT believe how different it handled, esp considering it's the same engine/chassis/driveline. could also not believe the curb weight that I didn't see until after the test drive, the x6 drives like its 1000lbs lighter than it is IMO. it has much more room in back than the exterior leads you to believe.
we have 2 infiniti FX that we love dearly, so the x6 body style feels like home to us, we didn't have any issues with the style, blindspots, etc…really going to enjoy it when it arrives!
