I wouldn't be surprised if it costs MORE! Why is she getting that big Navigator instead of the smaller Aviator? If it's just her and your Dad, and she only needs seating for an extra 3 folks, the Aviator should work well. I think it seats 5, like the Ford Explorer.
I have no idea...
I'll be sure and take some pictures of it, if she gets it. She could chicken out at the last minute....
I hope she lets me drive it!
