Many buyers of new '04 Navigators who had a budget on the lower end of the scale were content to go without a bell here and a whistle there. But many SUV-buyers, even those with no intention of ever leaving the pavement, are not willing to go without four-wheel drive, especially if they live in areas that frequently get snow.

The Luxury 4WD trim fit those buyers' needs, with its Control Trac four-wheel drive system. Although it offers the traditional 4x4 settings of 2 High, 4 High, and 4 Low, the system also has an Automatic setting, which functions like all-wheel drive.

Other equipment that came standard on this vehicle included heated power side mirrors, front and second-row captain's-style seats in leather, and a fully independent suspension with load-leveling. Available options were power-deployable running boards, heaters and coolers for the front seats, a sunroof, stability control, and a rear-seat DVD entertainment system.
