This year, the 2004 Ford Explorer Sport Trac is sold alone without its enclosed-cabin Ford Explorer Sport partner (the two-door enclosed version is no longer available). The Sport Trac offers the convenience of a four door 5-passenger SUV with the utility of an open 4ft. cargo bed. Available in four trim levels – the XLS, the XLT, the XLT Premium and an Adrenalin package – the Sport Trac boasts a durable 4.0-liter V6 as well as standard antilock 4-wheel disc brakes on all models. It also features an AM/FM/CD audio system and 29.6 cubic feet of cargo space.
