Automatic running boards and smooth ride.
I really love the ride that the navigator has, it's very smooth, I sit up high(I'm short), it has a sunroof, heated/cooled seats, the running boards go in & out when you open/close the doors. It has numbers on the driver side to create a code & you don't have to use your keys to unlock the doors. It has a third row seat which is really nice. I can haul stuff in the back if needed. I have out a bathtub in the back & a bathroom sink with cabinets, it is very room & good for traveling with family. Very reliable & comfortable. They only thing I don't like is the gas mileage. I like it so much that I am thinking about buying a newer navigator.
