LOADED ** XLT ** LOW MILEAGE, One in three compact-class pickups sold last year was a Ford Ranger. More than 5 million Rangers have been built since the first one rolled out in 1982. A rigid new chassis design in 1998 resulted in agile handling and a smooth ride., This year, fresh styling, new engines and redesigned components make the 2001 Ranger stronger, more practical, more convenient and more comfortable than last year.
