Ladies and Gentlemen:


         We have acted as special counsel to APCOA/Standard Parking, Inc., a
Delaware corporation (the "Company"), in connection with the preparation of the
Company's Registration Statement on Form S-4, registration number 333-50437 (the
"Registration Statement"), under the Securities Act of 1933, as amended (the
"Securities Act"), first filed with the Securities and Exchange Commission on
April 17, 1998, and as amended on June 9, 1998 and July 15, 1998, relating to an
offer to exchange (the "Exchange Offer") the Company's 9 1/4% New Senior
Subordinated Notes due 2008 (the "New Notes") for an equal principal amount of
the Company's outstanding 9 1/4 % Senior Subordinated Notes due 2008 (the

subordinated basis (the "New Note Guarantees") by, and will be joint and several
obligations of the following wholly owned

subsidiaries of the Company: Tower Parking, Inc., an Ohio corporation, Graelic,
Inc., an Ohio corporation, APCOA Capital Corporation, a Delaware corporation,
A-1 Auto Park, Inc., a Georgia corporation, Metropolitan Parking System, Inc., a
Massachusetts corporation, Events Parking Company, Inc., a Massachusetts
corporation, Standard Parking Corporation, an Illinois corporation, Standard
Parking Corporation IL, an Illinois corporation, Standard Auto Park, Inc., an
Illinois corporation, S&S Parking, Inc., a California corporation, Century
Parking, Inc., a California corporation, and Sentry Parking Corporation, a
California corporation (the above being referred to herein as the "Subsidiary
Guarantors").

         The Notes were issued, and the New Notes will be issued, under an
Indenture (the "Indenture") dated as of March 30, 1998, as amended as of July 6,
1998, among the Company, the Subsidiary Guarantors, and State Street Bank and
Trust Company, as Trustee (the "Trustee").

         In connection with this opinion, we have examined the Registration
Statement, the Indenture (included as Exhibit 4.1 to the Registration
Statement), the form of New Note (included as Exhibit 4.2 to the Registration
Statement), the form of New Note Guarantee (included as Exhibit 4.3 to the
Registration Statement) and originals or copies certified or otherwise
identified to our satisfaction of such other documents, corporate records and
other instruments as we have deemed necessary or appropriate for the purposes of
the opinion set forth herein.


         We have, with your approval, assumed the genuineness of all signatures,
the authenticity of all documents submitted to us as originals, the conformity
to authentic original documents of all documents submitted to us as certified,
facsimile, conformed, electronic, or photostatic copies and the authenticity of
the originals of such copies, and we have assumed the legal capacity of all
individuals executing such documents. In addition, as to all questions of fact
material to this opinion that have not been independently established, we have
relied upon certificates or comparable documents, and oral and written
statements and representations of, officers and representatives of the Company
and the Subsidiary Guarantors. We have not independently verified such
information and assumptions. Capitalized terms used and not defined herein shall
have the meanings ascribed to such terms in the Purchase Agreement (included as
Exhibit 1.1 to the Registration Statement).


         Based upon and subject to the foregoing, assuming that the Indenture
has been duly authorized, executed and delivered by, and represents the valid
and binding obligation of, the Trustee, and when the Registration Statement,
including any amendment thereto, shall have become effective under the
Securities Act and the Indenture shall have been duly qualified under the Trust
Indenture Act of 1939, as amended, and subject to the limitations and
qualifications set forth herein, we are of the opinion that:

         (1)      the New Notes, when duly executed and delivered by or on
                  behalf of the Company in the form contemplated by the
                  Indenture upon the terms set forth in

                  the Exchange Offer and authenticated by the Trustee or an
                  authenticating agent appointed by the Trustee in accordance
                  with the terms of the Indenture, will constitute the legal,
                  valid and binding obligations of the Company, enforceable
                  against the Company in accordance with their terms; and

         (2)      the New Note Guarantees, when duly executed and delivered by
                  or on behalf of the Subsidiary Guarantors in the form
                  contemplated by the Indenture upon the terms set forth in the
                  Exchange Offer, will constitute the legal, valid and binding
                  obligations of the Subsidiary Guarantors, enforceable against
                  the Subsidiary Guarantors in accordance with their terms;

subject, in each case, to (a) bankruptcy, insolvency, moratorium, reorganization
and other laws of general applicability, relating to or affecting creditors'
rights from time to time in effect; (b) application of general principles of
equity (regardless of whether considered in proceedings in equity or at law) and
the discretion of the court before which any proceeding therefor may be brought;
(c) standards of commercial reasonableness and the implied covenant of good
faith; and (d) public policy.

                  In addition, the opinions expressed herein are subject to the
following assumptions, exceptions, limitations, qualifications and comments:

         A.       We express no opinion as to the effect of the laws of any
                  jurisdiction other than the laws of the State of New York, and
                  the laws of the United States, wherein any holder of the New
                  Notes may be located which limit rates of interest that may be
                  charged or collected by such holder.

         B.       We express no opinion with respect to the lawfulness or
                  enforceability of:

                  (i)      provisions relating to delay or omission of
                           enforcement of rights or remedies, waivers of
                           defenses, or waivers of benefits of any usury,
                           appraisement, valuation, stay, extension, moratorium,
                           redemption, statutes of limitation, or other
                           non-waivable benefits bestowed by operation of law;

                  (ii)     exculpation provisions, provisions relating to
                           releases of unmatured claims, provisions purporting
                           to waive immaterial rights, severability provisions
                           and provisions similar in substance and nature to
                           those described in the foregoing clause (i) and this
                           clause (ii), insofar as any of the foregoing are
                           contained in the Indenture; and

                  (iii)    indemnification or contribution provisions to the
                           extent they purport to relate to liabilities from or
                           based upon negligence or any violation of, or relate
                           to rights of contribution or indemnification that are
                           violative of, any law, rule or regulation of the
                           public policy underlying any law, rule or

                           regulation (including any federal, state or
                           foreign securities law, rule or regulation).

         C.       Certain of the remedial provisions and waivers with respect to
                  the New Notes or the New Note Guarantees contained in the
                  Indenture may be unenforceable in whole or in part, but the
                  inclusion of such provisions does not affect the validity of
                  the New Notes or the New Note Guarantees, taken as a whole,
                  and the New Notes and the New Note Guarantees, taken as a
                  whole, together with the laws of the State of New York,
                  contain adequate provision for the practical realization of
                  the benefits of the obligations or guarantees created thereby.

         D.       We express no opinion as to the effect on the Indenture, the
                  New Notes, the New Note Guarantees or on the opinions
                  expressed herein, of any fraudulent conveyance laws. In
                  addition, we express no opinion as to the effects of either
                  (i) Section 548 of Title 11 of the United States Code or (ii)
                  Article 10 of the New York Debtor and Creditor Law, relating
                  to fraudulent transfers, on any obligation under the New Notes
                  or the New Note Guarantees.

                  We are admitted to practice only in the State of New York and
express no opinion as to the effect on the matters covered by this opinion of
the laws of any jurisdiction other than the laws of the State of New York and
the laws of the United States.

                  This opinion is rendered to you and is for your benefit in
connection with the Exchange Offer. This opinion may not be used or relied upon
by you for any other purpose, or furnished to, quoted to, or relied upon by any
other person, firm or corporation for any purpose, without our prior written
consent, except that we hereby consent (i) to the use of this opinion as an
Exhibit to the Registration Statement and to the reference to our firm under the
caption "Legal Matters" in the prospectus that is a part of the Registration
Statement and (ii) to your filing copies of this opinion as an Exhibit to the
Registration Statement with agencies of such states as you deem necessary in the
course of complying with the laws of such states regarding the Exchange Offer.
In giving any such consent, we do not hereby admit that we are in the category
of persons whose consent is required under Section 7 of the Securities Act.



                                     Very truly yours,


                                     /s/ Wachtell, Lipton, Rosen & Katz
