Well... My family is getting bigger and we need more spece than the ML has... I am researching the 2005 Lincoln Navigator Ultimate??? I looked at one up close, and I love the looks... very roomy, plush, luxurious, and power everything.... This thing even has power running boards that extend and retract when the passenger doors are opened and closed. I did not test drive one yet... Anybody has any experience with the 2004 or 2005 Navigator Ultimatate???
