McCandless buys a secondhand yellow Datsun in high school with money he earned from selling construction contracts one summer. His attachment to the car is so great that he vehemently refuses his parents’ offer to buy him a new one for his graduation. Even so, Chris abandons his beloved car in the desert, when salvaging it would mean prematurely ending his solo cross-country trip. He forgoes the convenience and safety of his car for the adventure and uncertainty of hitchhiking. Because of these events, the yellow Datsun symbolizes Chris’s pride in his hard work, his scorn for his parent’s materialism, and his rejection of a safe and convenient lifestyle.
