The new navi looks great in pictures, but in person, it doesn't have that same presence from the picture. Kinda bland actually. Yes, interior looks great. Nicely tarted up. But I'm in the LC because of what's under the skin. The Navi doesn't have that, except for the beefy motor. But the 300-series will get something comparable.
The Navigator also has a push button shifter. I never will understand what some auto designers are smoking when it comes to these new shifters.
