The Tracker moved under the Chevrolet nameplate for the 1998 model year when the Geo brand was discontinued, allowing the automaker to move into the growing mini sport-utility market. Almost half of Tracker owners are under age 35, which explains why Chevrolet calls Tracker "the sport utility for young-minded, adventurous, expressive buyers." Those who plan to attack the Rubicon Trail will be pleased to know that Tracker features a full ladder-type steel frame and nearly eight inches of ground clearance.
