REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
-------------------------------------------------------

Saturn Individual Savings Plan
for Represented Members:

We have audited the accompanying statements of net assets available for benefits
of the Saturn Individual Savings Plan for Represented Members (the "Plan") as of
December 31, 2004 and 2003, 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 standards of the Public Company
Accounting Oversight Board (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. The Plan is not required to have,
nor were we engaged to perform, an audit of its internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Plan's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, 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, such financial statements present fairly, in all material
respects, the net assets available for benefits of the Plan as of December 31,
2004 and 2003, and the changes in net assets available for benefits for the
years then ended in conformity with accounting principles generally accepted in
the United States of America.

As described in Note G, the Plan was merged into The General Motors Personal
Savings Plan for Hourly-Rate Employees in the United States ("PSP"), effective
as of January 1, 2005. All Plan assets were transferred directly into identical
funds within the PSP on December 31, 2004.

                         SATURN INDIVIDUAL SAVINGS PLAN
                             FOR REPRESENTED MEMBERS

                          NOTES TO FINANCIAL STATEMENTS

A. PLAN DESCRIPTION

Saturn Corporation ("Saturn"), a wholly-owned subsidiary of General Motors
Corporation ("GM" or the "Corporation"), has established a defined contribution
plan, the Saturn Individual Savings Plan for Represented Members (the "Plan").
Except for the purposes of investment of Plan assets, the Investment Funds
Committee of the Board of Directors of the Corporation acts as the Plan
fiduciary and, along with various officers, employees, and committees with
authority delegated by the Plan fiduciary, controls and manages the
non-investment operation and administration of the Plan subject to the
provisions of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"). General Motors Investment Management Corporation("GMIMCo")acts as the
Plan fiduciary for investment purposes. State Street Bank and Trust Company (the
"Trustee") acts as the trustee of the Plan. The Plan provides eligible
represented members with tax-deferred and after-tax voluntary savings
opportunities. The following brief description of the Plan is provided for
general information purposes only. Refer to the Plan document for a
comprehensive description of the Plan's provisions. As described more fully in
Note G, the Plan was merged into the GM Personal Savings Plan ("PSP") effective
as of January 1, 2005. All Plan assets were transferred on December 31, 2004.

    Participation
    Eligibility in the Plan is restricted to regular employees of Saturn
    compensated fully or partly by salary who are represented by the United
    Auto Workers ("UAW") or other labor organizations which have adopted the
    Plan. Employees who are classified as contract or leased employees are not
    eligible to participate. Eligible employees may participate in the Plan and
    accumulate savings as of the first day of employment. Employees on approved
    disability leaves of absence, or certain special leaves of absence, remain
    eligible to accumulate savings for a period of one year while on such
    leaves.

    Participant Contributions
    Participants direct the investment of their contributions (as well as
    Saturn matching contributions prior to January 1, 1992) into various
    investment options offered by the Plan. Participants may elect to
    contribute to the Plan in several ways:

     o Participants may contribute up to 60% for 2004 and up to 40% for 2003 of
       eligible earnings on an after-tax basis whereby the contributions are
       included in the participant's taxable income in the period of
       contribution ("After-Tax Savings").

     o Participants may contribute up to 60% in 2004 and 40% in 2003 of eligible
       earnings, not to exceed the annual Internal Revenue Service ("IRS")
       maximum deferral amount of $13,000 in 2004 and $12,000 in 2003 on a
       tax-deferred basis, whereby the contributions are excluded from the
       participant's taxable income until such amounts are distributed to the
       participant from the Plan ("Tax-Deferred Savings").

     o Participants may elect to combine the above contribution methods,
       provided the contribution limitations noted above are not exceeded.

     o Participants who have transferred to Saturn from another unit of the
       Corporation are allowed to transfer assets into the Plan from the General
       Motors Corporation Personal Savings Plan Trust.

     o Employees are permitted to make a rollover contribution equal to the
       taxable portion of cash proceeds received from a previous employer's
       qualified savings plan ("Rollover Contributions").

Certain costs of Plan administration are paid by Saturn.

                             FOR REPRESENTED MEMBERS
                    NOTES TO FINANCIAL STATEMENTS - Continued


    Investment Options
    The participants must direct in 1% increments, how their contributions are
    to be invested. The following investment options are available to the
    participants:

     o   General Motors $1-2/3 Par Value Common Stock Fund
     o   Promark Funds
     o   Mutual Funds

    During 2003, participant contributions could be invested into the GM Class H
    Common Stock Fund. Effective December 23, 2003, participant contributions
    could no longer be invested into the GM Class H Common Stock Fund.

    Description of Investment Options

    General Motors $1-2/3 Par Value Common Stock Fund - Under this investment
    option, contributions are invested by the Trustee in General Motors common
    stock. Assets held in this fund are expressed in terms of units and not
    shares of stock. Each unit represents a proportionate interest in all of the
    assets of the GM Common Stock Fund. The number of units credited to each
    participant's account within the Plan is determined by the amount of the
    participant's contributions and the purchase price of a unit in the GM
    Common Stock Fund. The value of each participant's account is determined
    each business day on which the New York Stock Exchange is open ("Business
    Day") by the number of units to the participant's credit, multiplied by the
    current unit value. The return on a participant's investment is based on the
    value of units, which, in turn, is determined by the market price of GM
    common stock, the amount of any dividends paid thereon, and by interest
    earned on short-term investments held by each fund.

    Promark Funds - There are Promark funds as investment options for
    participants in the Plan. These funds have a variety of investment
    strategies. Participants should refer to the prospectus for further
    information about the investment strategy of each fund, and the risks
    associated with each fund.

    Assets invested in the Promark funds are expressed in terms of units. The
    number of units credited to a participant's account within the Plan is
    determined by the amount of participant's contributions and the current
    value of each unit in the respective Promark fund. The value of each
    participant's account is determined each Business Day by the number of units
    to the participant's credit, multiplied by the current unit value.

    Mutual Funds - This investment option is comprised of many different mutual
    funds managed by Fidelity Investments, Neuberger Berman Management Inc.,
    Domini Social Investments LLC and SSgA Funds Management, Inc. Each mutual
    fund has a different objective and investment strategy. To pursue their
    objectives, the mutual fund managers invest in a wide variety of
    investments. Complete information about each mutual fund's objectives and
    investments is contained in that fund's prospectus. Effective November 1,
    2004, the following funds were added to the Plan: Fidelity
    Inflation-Protected Bond Fund and Fidelity Strategic Dividend & Income Fund.
    Also effective November 1, 2004, the following funds were eliminated from
    the Plan: Fidelity Trend Fund, Fidelity Disciplined Equity Fund, Fidelity
    Stock Selector Fund, Fidelity International Discovery Fund (formerly
    Fidelity International Growth & Income Fund), Fidelity Asset Manager,
    Fidelity Asset Manager: Income, and Fidelity Asset Manager: Growth.

                    NOTES TO FINANCIAL STATEMENTS - Continued


    Other Investments:

    EDS Common Stock Fund - Effective June 7, 1996, the net assets of Electronic
    Data Systems ("EDS") were split-off from the net assets of the Corporation.
    As a result, the Class E Common Stock Fund was changed to the EDS Common
    Stock Fund. No new contributions, loan repayments or exchanges may be made
    into the EDS Common Stock Fund. Dividends, if any, paid on the stock held by
    the Plan will be invested in the Promark Income Fund investment option.

    Assets held in this fund are expressed in terms of units and not shares of
    stock. Each unit represents a proportionate interest in all of the assets of
    this fund. The value of each participant's account is determined each
    Business Day by the number of units to the participant's credit, multiplied
    by the current unit value. The return on a participant's investment is based
    on the value of units, which, in turn, is determined by the market price of
    EDS common stock and by the interest earned on short-term investments held
    by the fund.

    DIRECTV Group Common Stock Fund - Effective December 23, 2003, GM Class H
    stock was replaced with DIRECTV Group Common Stock and News Corporation
    Preferred ADSs at the ratio of 84% and 16%, respectively. The DIRECTV Group
    Common Stock Fund will remain as an investment option; however, no further
    contributions or exchanges from any other investment option into the DIRECTV
    Group Common Stock Fund will be permitted during that time. Dividends, if
    any, paid on the stock held by the Plan will be invested in the Promark
    Income Fund investment option.

    Assets held in this fund are expressed in terms of units and not shares of
    stock. Each unit represents a proportionate interest in all of the assets of
    this fund. The value of each participant's account is determined each
    Business Day by the number of units to the participant's credit, multiplied
    by the current unit value. The return on a participant's investment is based
    on the value of units, which, in turn, is determined by the market price of
    the DIRECTV Group common stock and by the interest earned on short-term
    investments held by the fund.

    News Corporation Non-Voting Common Stock Fund - Effective October 26, 2004,
    shareholders approved the reorganization of News Corporation. As a result,
    the News Corporation Preferred ADS fund was eliminated and replaced by News
    Corporation Non-Voting Common Stock Fund in the Plan.

    On November 4, 2004, New Corporation Preferred ADSs ceased trading on the
    New York Stock Exchange. Holders of Preferred ADSs received in exchange two
    shares of News Corporation Non-Voting Common Stock for each ADS held.
    Accordingly, the News Corporation Preferred ADS Fund was eliminated and the
    value of units in such fund were converted into units of a new commingled
    fund known as the News Corporation Non-Voting Common Stock Fund. The News
    Corporation Non-Voting Common Stock Fund will remain as an investment
    option; however, no further contributions or exchanges from any other
    investment option into the News Corporation Non-Voting Common Stock Fund
    will be permitted. Dividends, if any, paid on the stock held by the Plan
    will be invested in the Promark Income Fund investment option.

    Assets held in this fund are expressed in terms of units and not shares of
    stock. Each unit represents a proportionate interest in all of the assets of
    this fund. The value of each participant's account is determined each
    Business Day by the number of units to the participant's credit, multiplied
    by the current unit value. The return on a participant's investment is based
    on the value of units, which, in turn, is determined by the market price of
    News Corporation Non-Voting Common Stock Fund and by the interest earned on
    short-term investments held by the fund.

    Delphi Common Stock Fund - On May 28, 1999, the Corporation completed the
    spin-off of Delphi Corporation ("Delphi"). In connection with that spin-off,
    Delphi common stock was distributed to holders of GM $1-2/3 Par Value Common
    Stock. Such distribution required the addition of the Delphi Common Stock
    Fund as an investment option. The Delphi Common Stock Fund will remain as an
    investment option; however, no further contributions or exchanges from any
    other investment option into the Delphi Common Stock Fund will be permitted
    during that time. Dividends, if any, paid on the stock held by the Plan will
    be invested in the Promark Income Fund Investment Option.

    Assets held in this fund are expressed in terms of units and not shares of

    on the value of units, which, in turn, is determined by the market price of
    Delphi common stock and by interest earned on short-term investments held by
    the fund.

    Raytheon Common Stock Fund - Effective December 17, 1997, GM spun-off the
    defense electronics business of Hughes Electronics Corporation, at the time,
    a subsidiary of the Corporation ("Hughes Defense"), to holders of GM $1-2/3
    Par Value and GM Class H common stock, which was immediately followed by the
    merger of Hughes Defense with Raytheon Company. In connection with the above
    transaction, Raytheon common stock was distributed to holders of the GM
    $1-2/3 Par Value and Class H common stocks.

    Such distribution required the addition of the Raytheon Common Stock Fund as
    an investment option. No new contributions or exchanges from any other
    investment options into the Raytheon Common Stock Fund are permitted.
    Dividends, if any, paid on the stock held by the Plan will be invested in
    the Promark Income Fund investment option.

    Assets held in this fund are expressed in terms of units and not shares of

                    NOTES TO FINANCIAL STATEMENTS - Continued


    GM has chosen to invest the General Motors $1 2/3 Par Value Common Stock
    Fund, the EDS Common Stock Fund, the Raytheon Common Stock Fund, the DIRECTV
    Group Common Stock Fund, the News Corporation Non-Voting Common Stock Fund,
    and the Delphi Common Stock Fund in commingled funds managed by State Street
    Bank and Trust ("State Street') State Street is responsible for anticipating
    liquidity needs and maintaining sufficient cash levels to process
    participant transactions, determining the daily number of shares of each
    individual common stock to be purchased or sold, and obtaining the best
    prices for any purchases or sales.

    Participant Loans - Participants may borrow once per calendar year from both
    their Deferred and After-Tax Savings assets. The amount and term of the
    loans are limited under the Plan. The loan interest rate is established once
    each quarter at a rate equal to the prime lending rate as of the previous
    quarter-end as published by the Wall Street Journal and will apply to all
    new loans issued. Loan repayments are generally made through after-tax
    payroll deductions and are invested in the same discretionary investment
    options that the Participant originally selected for their savings
    contributions. Interest paid on the loans is credited back to the borrowing
    participant's account in the Plan. Loans not repaid within the provisions of
    the Plan are deemed to be distributions from participant's accounts. At
    December 31, 2003, loans to participants were $14,660,929.

    Vesting
    Participant contributions vest immediately. Saturn matched participant
    contributions were made through January 1, 1992 and earnings thereon vest
    fully upon the attainment of five years of service, death, total and
    permanent disability, or retirement. Effective January 1, 1992, matching of
    participant contributions by Saturn was discontinued.

    Distributions
    Participants may generally withdraw their Tax-Deferred Savings after they
    reach age 59-1/2 or prior to age 59-1/2 for Financial Hardship, as defined
    in the Plan document. After-Tax Savings, vested Saturn matched
    contributions, and related earnings may be withdrawn any time upon a
    participant's request. The funds that represent a hardship distribution must
    conform to standards required by the Internal Revenue Service. Upon
    termination of employment, a final distribution of assets is made unless
    termination is by retirement or the participant's account exceeds $1,000. In
    those instances, the distribution may be deferred until April 1 of the year
    after the participant reaches the age of 70-1/2. Participants who continue
    working beyond reaching the age of 70-1/2 are not required to begin
    distribution.

    There were no distributions payable to participants included in net assets
    available for benefits as of December 31, 2004 and 2003.

    Fund Exchanges
    Participants may exchange funds between investment options on any business
    day on which the New York Stock Exchange is open ("Business Day").

    Redemption Fees - Effective June 1, 2003, a 1% short-term trading fee on the
    Promark International Equity Fund and the Promark Emerging Markets Equity
    Fund was instituted. From time to time, certain funds may impose a
    redemption fee if an investment is held for less than a stated period. If
    applicable, these fees are disclosed in the individual mutual fund
    prospectuses which contain additional information about each fund. The
    redemption fees are paid to the respective funds and help protect the funds'
    performance and shareholders by discouraging frequent trading in response to
    short-term market fluctuations.

B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies followed in the preparation of the Plan's
financial statements are as follows:

    o  The financial statements of the Plan are prepared under accounting
       principles generally accepted in the United States of America using the
       accrual method of accounting.

    o  Investments are stated at fair value, except for benefit-responsive
       investment contracts, which are stated at contract value which
       approximates fair value, and loans to participants, which are stated at
       cost which approximates fair value. Fair values are calculated by
       reference to published market quotations, where available; where not
       available for certain investments, various bases, including cost, are
       used in determining estimates of fair values. Contract value represents
       contributions and withdrawals made under the investment contracts, plus
       credited earnings, which are net of expenses charged to the synthetic
       contract.

    o Security transactions are recorded on the trade date.

    o  Investment income is recognized as earned based on the terms of the
       investments and the periods during which the investments are owned by the
       Plan.

    o  The preparation of financial statements in accordance with accounting
       principles generally accepted in the United States of America requires
       management to make estimates and assumptions that affect the reported
       amounts of net assets and changes therein. Actual results could differ
       from those estimates. The Plan utilizes various investment instruments.
       Investment securities, in general, are exposed to various risks, such as
       interest rate, credit, and overall market volatility. Due to the level of
       risk associated with certain investment securities, it is reasonably
       possible that changes in the values of investment securities will occur
       in the near term and that such changes could materially affect the
       amounts reported in the financial statements.

C. INVESTMENTS

All of the investments in the Plan are held in the General Motors Savings Plan
Master Trust (the "Master Trust") as more fully described in Note D. The
investment in the Master Trust is both participant-directed and non-participant
directed.

The synthetic guaranteed investment contracts ("Contracts") owned by the Plan
and held in the Master Trust are recorded at contract value and are fully
benefit-responsive in accordance with the American Institute of Certified Public
Accountants' Statement of Position 94-4, Reporting of Investment Contracts Held
by Health and Welfare Benefit Plans and Defined Contribution Pension Plans. The
Contracts are included in the financial statements, within the Promark Income
Fund, at contract value as reported to the Master Trust by the insurance
company. Contract value represents contributions and withdrawals made under the
investment Contracts, plus credited earnings, that are net of expenses charged
to the synthetic contract. Participants may ordinarily direct the withdrawal of
all or a portion of their investment at contract value. Contract value of such
Contracts approximates fair value as of December 31, 2004 and 2003. Synthetic
guaranteed investment contracts operate similarly to

                                       11

                    NOTES TO FINANCIAL STATEMENTS - Continued


a separate account investment contract, except that the assets are placed in a
trust (with ownership by the Master Trust) rather than a separate account of the
contract issuer.

The Contracts provide for prospective crediting interest rate adjustments based
on the interest earnings and fair value of the underlying trust assets. The
crediting interest rates are reset quarterly and the Contracts include wrappers
that provide that the crediting interest rates cannot be less than zero. The
average crediting interest rate of the synthetic guaranteed investment contracts
as of December 31, 2004 and 2003 was approximately 4.79% and 5.12%,
respectively. The wrappers are entered into by the Master Trust to stabilize the
income generation of the fund.

The average yield for the synthetic investment contracts within the Promark
Income Fund was approximately 4.5% and 4.9% for the years ended December 31,
2004 and 2003, respectively. There are no reserves against the contract value
for credit risk of the contract issuer or otherwise.

D. THE MASTER TRUST

The Corporation established the Master Trust pursuant to a trust agreement among
the Corporation, Saturn Corporation, and State Street Bank and Trust, as trustee
of the funds, in order to permit the commingling of trust assets of several
employee benefit plans for investment and administrative purposes. The assets of
the Master Trust are held by State Street Bank and Trust.

Employee benefit plans participating in the Master Trust as of December 31, 2004
include the following:

    o   General Motors Savings-Stock Purchase Program for Salaried Employees in
        the United States
    o   The General Motors Personal Savings Plan for Hourly-Rate Employees in 
        the United States ("PSP")
    o   Saturn Individual Savings Plan for Represented Members which merged 
        into the PSP on December 31, 2004 (Note G)
    o   General Motors Income Security Plan for Hourly-Rate Employees

Each participating employee benefit plan has an undivided interest in the net
assets and changes therein of each of the Master Trust investment options in
which the respective plan participates.

The net investment income of the commingled Master Trust investment funds (the
GM $1-2/3 Par Value Common Stock Fund, the EDS Common Stock Fund, the Raytheon
Common Stock Fund, the Delphi Common Stock Fund, the News Corporation Non-Voting
Common Stock Fund, the DIRECTV Group Common Stock Fund and the Promark Funds) is
allocated by the trustee to each participating plan based on that plan's
interest in each commingled Master Trust investment fund, as compared with the
total interest in each commingled Master Trust investment fund of all the
participating plans at the beginning of the month. For all other investment
options, the net investment income is separately earned by the respective
employee benefit plan, and is thus recorded separately in the accounting records
of the respective plan.

The Plan had no interest in the Master Trust as of December 31, 2004. As of
December 31, 2003, the Plan had approximately a 1.60% interest in the Master
Trust.

E. FEDERAL INCOME TAXES

By a letter dated May 27, 2003, the IRS has determined and informed Saturn that
the Plan and related trust are designed in accordance with applicable sections
of the Internal Revenue Code ("IRC"). The Plan's administrator and the Plan's
tax counsel believe that the Plan is designed and is currently being operated in
compliance with the applicable requirements of the IRC, and therefore no
provision for income taxes has been included in the Plan's financial statements.

F. RELATED PARTY TRANSACTIONS

The Plan and Master Trust enter into certain related party transactions. These
generally include investments with trustees, fund managers, the Corporation and
its subsidiaries. Such transactions are within the scope of the investment
guidelines.


G. PLAN MERGER

The Plan was merged into the PSP, effective as of January 1, 2005. All plan
assets transferred directly into identical funds within the PSP on December 31,
2004.
