I think the one that they're talking about is the new 2003 Aviator the "Explorer-esque" SUV. It has more hp than the GM Mid-size trio (304??), and more features than its Mercury cousin. Better deal!
The new Navigator is not that impressive, according to the reviews that I accumulated, the engine lacks punching-power to carry its heavy load and they say (performance wise) the Caddy Escalade is better (this months Motor Trend mag.). But anything else is is quite accomodating (power hatch, power fold 3rd row seats, power fold stepboards).
