NAVISTAR PARTS TURNS TRASH INTO CASH

Industry-unique OnCommand™ Parts Return Program Offers Cash for Customers’ Obsolete and Surplus Parts.

WARRENVILLE, Ill. (Aug. 1, 2011) — Navistar (NYSE:NAV) is the only truck and engine manufacturer to offer a program that allows customers to return unused excess and obsolete parts from their inventory with the potential to earn full reimbursement through future parts purchases. The OnCommand™ Parts Return Program offers a direct monetary benefit to customers who would otherwise dispose of old or unused parts in scrapyards for pennies on the dollar.

By working with their U.S. or Canadian International or IC Bus dealer, customers can return unused inventory, overstocks or obsolete parts for any make or model vehicle in order to capitalize on available credit, regardless of their prior purchase history.

With the initial parts redemption, customers receive 25 percent of the value of the products returned to use toward future parts purchases. Customers are required to purchase a predetermined amount of parts over a specified period of time as part of their Parts Return Program agreement. Upon completion of this agreement, customers will receive the full credit amount for their return.

"The OnCommand Parts Return Program goes beyond a loyalty program and becomes a way that our customers can secure real working capital from unused outdated parts," said Michael Cancelliere, senior vice president and general manager for Navistar Parts in North America. "If someone turns in $10,000 worth of parts that have just been gathering dust, we take them and immediately give them $2,500 in cash or credit toward their parts purchases. They can then earn the full value of those return parts by fulfilling program purchase commitments."

"A lot of our customers are looking for ways to improve their bottom line," said Joe Coconate, outside parts sales representative for Chicago International. "With the OnCommand Parts Return Program, parts that haven't been used for years can be converted to real money for our customers."

The OnCommand Parts Return Program will provide earned credit through any card in Navistar's Fleet Charge® network. The Fleet Charge program is used to track parts purchases and corresponding credit amounts.

Customers interested in participating in the OnCommand Parts Return Program can contact the parts department at their local U.S. or Canadian International truck or IC Bus dealership. More information is available online at www.navistarpartsandservice.com
