Other Cautionary Legends The financial information herein contains both audited and preliminary/unaudited and has been prepared by management in good faith and based on current company data. Certain Non-GAAP measures are used in this presentation to assist the reader in understanding our core manufacturing business. We believe this information is useful and relevant to assess and measure the performance of our core manufacturing business as it illustrates manufacturing performance without regard to selected historical legacy costs (i.e. pension cost) and other expenses that may not be related to the core manufacturing business. Management often uses this information to assess and measure the performance of our operating segments. A reconciliation to the most appropriate GAAP number is included in the appendix of this presentation.

Products of Distinction "If Spiderman hauled freight, this is what he'd drive. International says its new LoneStar class 8 highway truck is a "game-changer". It's true that this chromed-up tractor is like nothing you've seen motoring down the highway. It may look like it belongs on a movie set - -- or a certain webbed superhero's garage -- but International insists its new flagship product is as much a work truck as it is a head-turner. Unveiled for the first time at this week's Chicago Auto Show, the LoneStar features arguably the most unique aerodynamic and front grille design in the industry.

Appendix

Frequently Asked Questions Q1: What is the status of the GM opportunity? A: As for the potential acquisition of the General Motors medium-duty truck business, we are diligently working to make sure that any acquisition would be in the best interests of the company and its shareholders but given the status of negotiations and our confidentiality obligations, we are not in a position at this time to make any further public announcements on this matter. Q2: Why did you file the 2006 results as an 8K versus a 10K? A: To be expedient and adhere to our plan to be current by mid-year; we responded to what we thought the market was seeking and determined that we would report 2006 audited financials under an 8K. This allowed us to tighten the timeline while still providing the pertinent information our shareholders need-financial statements, MD&A and other valuable disclosures. Keep in mind that since we expect to file the 2007 10K relatively soon, the 2006 8K will have a relatively short "shelf life." The important point is we followed the same internal certification processes and KPMG followed the same standards for providing their audit opinion on the financial statements as if we had filed a 10k. We continue our ongoing dialogue with the SEC. They are aware of our process and supportive of our goal to be current by mid-year. Q3: What should we assume as the total on capital expenditures for 2008? A: For 2008, excluding our NFC and Dealcor acquisition of vehicles for leasing, we still expect our capital expenditures to be within the lower half of the $250 million to $350 million range. We continue to fund our strategic programs.

Frequently Asked Questions Q4: What is in your Dealcor debt? A: Dealcor debt is comprised of wholesale (floor plan) financing and also retail financing on lease and rental fleets. Q5: How many Dealcor dealers did you have as of January 31, 2008? A: Of our 303 primary NAFTA dealers, 22 were Dealcor dealers as of January 31, 2008. We expect to have 19 Dealcor dealers on October 31, 2008. Q6: What percentage of Navistar's parts revenue is proprietary versus all makes? A: Approximately 40% of part's revenue is proprietary. Q7: What do you finance at Navistar Finance Corporation (NFC)? A: NFC is a commercial financing organization that provides wholesale, retail and lease financing for sales of new and used trucks sold by the company. NFC also finances the company's wholesale accounts and selected retail accounts receivable. Sales of new truck related equipment (including trailers) of other manufacturers are also financed. Q8: Have you seen any year-over-year steel, precious metals and resin cost increases in 2008? A: Steel and Other Commodities - Commodity price increases, particularly for aluminum, copper, precious metals, resins, and steel have contributed to substantial cost pressures in the industry as well as from our suppliers. Cost increases related to steel, precious metals, resins, and petroleum products totaled approximately $184 million, $178 million, $90 million, and $7 million for 2005, 2006, 2007, and the first three months of 2008, respectively, as compared to the corresponding prior year period. Generally, we have been able to mitigate the effects of these cost increases via a combination of design changes, material substitution, resourcing, global sourcing efforts, and pricing performance, although we do not specifically identify these items on customer invoices. In addition, although the terms of supplier contracts and special pricing arrangements can vary, generally a time lag exists between when we incur increased costs and when we might recoup them through increased pricing. This time lag can span several quarters or years, depending on the specific situation.

Frequently Asked Questions Q9: What is the status of your hybrid program? A: We were the first manufacturer to bring this technology to on line production and currently are producing our DuraStar hybrid trucks well as a hybrid version of our industry-leading IC Bus-brand school bus. To date, we have built and fielded over 100 units covering medium truck, bus, and package car applications. We have over 1.5 million miles of validation testing and are in the process of training our entire dealer organization on selling and servicing this new product. Q10: The future of diesel transportation is being impacted by environmental and energy issues such as fuel efficiency, climate change and clean air. How is Navistar responding to these growing influences? A: Navistar and its production units are fully engaged. Aerodynamic efficiency is the single most important issue to address to improve the fuel economy of on-highway trucks. International ProStar is the industry's most aerodynamic and fuel efficient Class 8 truck. We do extensive development in wind tunnels and work hard to achieve industry-leading aero-efficiency. And our recently introduced International LoneStar is setting a whole new standard of aero-efficiency among premium Class 8 trucks. We also believe hybrid technology will be a large part of the national response to climate change and fuel use and we are raising our role as a contributor to energy efficient transportation solutions in the commercial truck, commercial bus and school bus businesses. We are leveraging the natural fuel efficiency of diesel engines and vehicles in several key moves. We are building on our record as the leader in Green Diesel Technology, where Navistar set the pace for the industry in achieving this year's historically low emission requirements. We have advanced the standard of efficiency with our new ProStarTM truck. And we are well into the important wave of customer interest in hydraulic and electric hybrids. Navistar was recognized for leadership in the development of hybrid advanced technology in California, receiving the Blue Sky Award for 2007 from WestStart-CALSTART.

SEC Regulation G The above non-GAAP financial measures are unaudited and reflect a 2007 change in segment reporting methodology. This presentation is not in accordance with, or an alternative for, U.S. generally accepted accounting principles (GAAP). The non-GAAP financial information presented herein should be considered supplemental to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. However, we believe that non-GAAP reporting, giving effect to the adjustments shown in the reconciliation above, provides meaningful information and therefore we use it to supplement our GAAP reporting by identifying items that may not be related to the core manufacturing business. Management often uses this information to assess and measure the performance of our operating segments. We have chosen to provide this supplemental information to investors, analysts and other interested parties to enable them to perform additional analyses of operating results, to illustrate the results of operations giving effect to the non-GAAP adjustments shown in the above reconciliations, to provide an additional measure of performance.
