                         Report of Independent Auditors

To Participants and Administrator of
United Rentals, Inc. 401(k) Investment Plan

We have audited the accompanying statements of net assets available for benefits
of United Rentals, Inc. 401(k) Investment Plan as of December 31, 2000 and 1999,
and the related statements of changes in net assets available for benefits for
the years then ended. 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.

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.

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 1999, and the changes in its net assets available for
benefits for the years then ended, in conformity with accounting principles
generally accepted in the United States.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedule of assets
held at end of year as of December 31, 2000, is presented for purposes of
additional analysis and is not a required part of the financial statements but
is 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. This supplemental schedule is the responsibility of the
Plan's management. The supplemental schedule has been subjected to the auditing
procedures applied in our audits of the financial statements and, in our
opinion, is fairly stated in all material respects in relation to the financial
statements taken as a whole.

1.  Description of the Plan

The following description of the United Rentals, Inc. 401(k) Investment Plan
(the "Plan") provides only general information. Participants should refer to the
Plan document for a more complete description of the Plan's provisions.

General

The Plan is a defined contribution plan, which was established by United
Rentals, Inc. (the "Company"). All employees of the Company are eligible to
participate in the Plan on the first day of the month following completion of
six months of employment (with a minimum of 30 hours of service per week and
provided that they have reached the minimum age of 21 years). The Plan has been
designed to allow tax deferred contributions by the participants with
discretionary Company contributions. The Plan is subject to provisions of the
Employee Retirement Income Security Act of 1974 (ERISA).

Contributions

Participants may elect to contribute up to 15% of their annual wages paid by the
Company, limited to $10,500 per annum in 2000 and $10,000 per annum in 1999.
Participants can suspend their contributions at any time and still remain in the
Plan. Participants can resume contributions (after one year) and can change
their elected contribution rate on January 1, April 1, July 1 and October 1 of
each year.

The Company may contribute a discretionary amount to the Plan which is
determined annually by the Board of Directors of the Company. During the years
ended December 31, 2000 and 1999, the Company contributed 50% of the first 6% of
each participant's compensation up to a maximum contribution of $1,500.

Participant Accounts

Each participant account is credited with the participant's contribution, the
Company's discretionary contribution, if any, and an allocation of Plan
earnings. Allocations are based on the account balance of the participants.

Vesting

Participants are always 100% vested in their contributions plus actual earnings
thereon. Company contributions plus actual earnings thereon begin vesting 20%
per year after one year of service and are 100% vested after five years of
service (365 days minimum

                                                                               4

service per year). Forfeitures of Company contributions, which aggregated
$404,662 for 2000 and $455,733 for 1999, are applied to reduce future Company
contributions or to pay for Plan administrative expenses.

Investment Options

Participants may direct their elective contributions and the related Company
discretionary contributions into any of the Plan's investment options. From
January 1, 1999 to April 30, 2000 all investment options were through the Plan's
trustee, Merrill Lynch and Company. Effective May 1, 2000, the Plan changed its
trustee to T. Rowe Price Retirement Plan Services, Inc.

Participants Loans

Participants may borrow from their vested balances in the Plan, subject to
certain restrictions and limitations set forth in the Plan document and the
Internal Revenue Code. Loan terms range from one to five years for personal
loans and up to a reasonable period of time as established by the Plan
Administrator for the purchase of a primary residence. The loans are secured by
the vested balance in the participant's account and bear interest at a rate
determined by the Plan Administrator. Interest rates range from 7.78% to 10.50%.
Principal and interest are paid ratably through payroll deductions.

Distributions and Withdrawals

A participant may not make withdrawals from their account prior to attaining age
59 1/2, except in the event of retirement, termination of employment or proven
hardship. Hardship withdrawals must be authorized by the Plan Administrator and
are subject to the requirements and limitations set forth in the Plan document,
the Internal Revenue Code and the regulations thereunder.

Plan Termination

Although it has not expressed any intent to do so, the Company has the right
under the Plan to discontinue its contributions at any time and terminate the
Plan subject to the provision of ERISA. In the event that the Plan is
terminated, the participants will become 100% vested in their accounts.

                                                                               5

1.  Description of the Plan (continued)

Administrative Expenses

All of the Plan's administrative expenses are paid by the Company. All
investment related expenses are charged directly to the participants' accounts.

2.  Summary of Significant Accounting Policies

Basis of Accounting

The Plan's financial statements are prepared on the accrual basis of accounting.

Investments

The Plan's investments are stated at fair value. Participant loans are valued at
their outstanding principal balances, which approximate fair value.

Use of Estimates

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

3.  Income Tax Status

The Plan has applied for but has not received a determination letter from the
Internal Revenue Service stating that the Plan is qualified under Section 401(a)
of the Internal Revenue Code. The Plan Administrator believes that the Plan is
qualified and, therefore, the related trust is exempt from taxation. The Company
has indicated that it will take the necessary steps, if any, to maintain the
Plan's qualified status.

                                                                               6
