With the 2006 introduction of its mid-size Zephyr (now MKZ) sedan and a nicely reworked Navigator SUV for 2007, Lincoln is on a bit of a roll. This very nice new MKX crossover utility vehicle (CUV) is a welcome addition to its stable. Lincoln is far from first to the car-based "crossover" party, but this all-new entry is fresh in terms of its generally excellent blend of style, function, features and driving dynamics. One thing it does not havesomewhat surprisingly, given its fairly substantial sizeis an available third-row seat. Three-seat CUV seekers can check out Ford's less expensive and more conservatively styled Freestyle, but there is no Lincoln version of that.
