Report of Independent Auditors

The Administrator of the
  PACCAR Inc Savings Investment Plan

We have audited the accompanying statements of net assets available for benefits of the PACCAR Inc Savings Investment Plan as of December 31, 2000 and 1999, and the related statement of changes in net assets available for benefits for the year ended December 31, 2000. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits.

Except as explained in the following paragraph, we conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

As permitted by 29 CFR 2520.103-8 of the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974, investment assets held by Fidelity Management Trust Company, the Trustee of the Plan, and transactions in those assets were excluded from the scope of our audit of the Plan's 1999 financial statements, except for comparing the information provided by the trustee, with the related information included in the financial statements.

Because of the significance of the information that we did not audit, we are unable to, and do not, express an opinion on the Plan's financial statements as of December 31, 1999. The form and content of the information included in the 1999 financial statements, other than that derived from the information certified by the Trustee, have been audited by us and, in our opinion, are presented in compliance with the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan at December 31, 2000, and changes in its net assets available for benefits for the year then ended in conformity with accounting principles generally accepted in the United States.

Our audit of the Plan's financial statements as of and for the year ended December 31, 2000, was made for the purpose of forming an opinion on the financial statements taken as a whole. The supplemental schedules of assets (held at end of year) as of December 31, 2000 and reportable transactions for the year then ended are presented for the purpose of additional analysis and are not a required part of the financial statements but are supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. These supplemental schedules are the responsibility of the Plan's management. The supplemental schedules have been subjected to the auditing procedures applied in the audit of the financial statements for the year ended December 31, 2000, and, in our opinion, are fairly stated in all material respects in relation to the financial statements taken as a whole.

PACCAR Inc
Savings Investment Plan

Notes to Financial Statements

December 31, 2000

1.  Description of the Plan

    The PACCAR Inc Savings Investment Plan (the Plan) is a defined contribution plan covering substantially all nonunion employees of PACCAR Inc and its participating subsidiaries (the Company). Participants are eligible to become a member of the Plan after completion of 30 days of service. Participants are eligible to receive employer contributions after 1 year of service. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA) and the Internal Revenue Code of 1986 (Code). Participants should refer to the Plan document for a complete description of the Plan's provisions.

Contributions

    Participants may contribute and allocate a selected percentage of their compensation annually (as defined in the Plan document). Participant contributions are voluntary and limited to an amount not less than 2% or greater than the lesser of 20% of their respective compensation or the Internal Revenue Service-mandated annual maximum of $10,500 in 2000 and $10,000 in 1999. Participant contributions to the Plan are excluded from the participants' current taxable earnings in accordance with Code Section 401(k).

    The Company matches participant contributions up to 5% of the employees' respective compensation, of which all contributions are applied toward the purchase of PACCAR Inc common stock. The Company may suspend or reduce its contributions when its "Consolidated Net Earnings," as defined by the Plan, are less than 8% of the Company's "Capital Base," as defined by the Plan. The Company match is contributed and allocated to the participants' accounts on the last day of the Plan year. Upon reaching 50 years of age, participants who have completed 5 or more years of service have a single opportunity to transfer to any one or more of the other investment options available under the Plan any whole percentage of the value of his or her PACCAR Inc common stock account. Any future Company contributions allocated to such member will continue to be credited to the member's PACCAR Inc common stock account.

Participant Accounts

    Individual accounts are maintained for all Plan participants that reflect their contributions and related Company contributions to the Plan and any earnings or losses on the Plan's investments. The benefit to which the participant is entitled is the benefit that can be provided from the participant's account.

Vesting

    Plan participants are fully vested in their accounts at all times for amounts contributed by the participants and the Company.

Investment Options

    Upon enrollment in the Plan, a participant may direct employee contributions in whole percentage increments to any of the Plan's fund options. Participants may change their investment options daily.

4


    Prior to 2001, PACCAR Inc common stock was not an investment option for participants, but was used only for the Company match. Effective January 2, 2001, the investment options were expanded to include direct investment by participants in PACCAR Inc common stock.

Participant Loans

    Participants may borrow from their individual accounts a minimum of $1,000, up to the lesser of $50,000 or 50% of their account balance, exclusive of the portion of the account balance resulting from the investment in PACCAR Inc common stock. Loan terms range from 1 to 5 years, or up to 15 years for the purchase of a primary residence. The loans are secured by the balance in the participant's account and bear interest equal to the prime rate plus 1%, as determined monthly by the Plan administrator. Interest rates ranged from 7.00% to 10.50% during 2000. Principal and interest are repaid through payroll deductions at least on a quarterly basis.

Benefit Payments

    In the case of terminations on or after age 55, benefits are paid at the participant's election in a lump sum or in annual installments. In the case of terminations before age 55, benefits are paid in a lump-sum distribution. Participants may elect to receive PACCAR Inc common stock for their vested interest in PACCAR stock.

Plan Termination

    It is the intention of the Company that the Plan will continue indefinitely. However, should the Company elect to terminate the Plan, the termination date shall be treated as the valuation date, and the balances in the participants' accounts will be distributed to them.

Expenses

    Third-party management fees are charged to the Plan, and the Company pays all other expenses of the Plan's administration.

2.  Summary of Accounting Policies

Basis of Accounting

    The financial statements have been prepared on the accrual basis of accounting.

Investment Valuation and Income Recognition

    The Plan's investments are stated at fair value. The fair value of the participation units owned by the Plan in commingled trust funds and mutual funds is based on quoted market prices, which represent the net asset value of the underlying investments as reported by the funds on the last business day of the Plan year. Investments in securities traded on a national securities exchange are valued at their market prices on the last business day of the Plan year. The money market fund is valued at cost, which approximates fair value. Participant loans are recorded at their outstanding balances, which approximate fair value.

    Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date.

5


Use of Estimates

    The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates.

Risks and Uncertainties

    The Plan provides for various investment options. Investment securities are exposed to various risks, such as interest rate, market, and credit. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks in the near term would materially affect the value of participants' account balances and the amounts reported in the statements of net assets available for benefits and the statement of changes in net assets available for benefits.

3.  Investments

    The Fidelity Management Trust Company (the Trustee) holds the Plan's investments and executes all investment transactions.

    Investments held at December 31, 1999, as disclosed in the financial statements, were obtained or derived from information supplied to the Plan Administrator and certified as complete and accurate by the Trustee.

    During 2000, the Plan's investments (including investments purchased, sold, as well as held during the year) appreciated (depreciated) in fair value as determined by quoted market prices as follows:

5.  Income Tax Status

    The Plan has received a determination letter from the Internal Revenue Service dated July 8, 1994, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the Code) and, therefore, the related trust is exempt from taxation. Subsequent to this issuance of the determination letter, the Plan was amended. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan Administrator believes the Plan is being operated in compliance with the applicable requirements of the Code, and, therefore, believes that the Plan, as amended, is qualified and the related trust is tax exempt.

7


6.  Transactions with Parties-in-Interest

    The Plan invests in the stock of the Plan's Sponsor, PACCAR Inc, which is purchased by the Trustee on the open market at fair value. During 2000, the Plan made purchases totaling $27,804,156 of PACCAR Inc stock and sales totaling $13,950,839. During 1999, the Plan made purchases totaling $23,928,798 shares of PACCAR Inc stock and sales totaling $16,045,902. The Plan accrued dividends on this stock totaling $11,084,451 and $11,435,854 in 2000 and 1999, respectively. Dividends receivable as of December 31, 2000 and 1999 are $5,085,329 and $7,629,117, respectively.
