EXHIBIT 10.16

               STOCK PURCHASE, VESTING AND REPURCHASE AGREEMENT

          This STOCK PURCHASE, VESTING AND REPURCHASE AGREEMENT (this
"Agreement") is entered into as of October 19, 1998, between City Truck
Holdings, Inc., a Delaware corporation (the "Company"), and A. William Cavalle
("Investor" or "you").  In consideration of the agreements contained herein, the
parties agree as follows:

          1.  Issuance.  The Company agrees to issue to you, and you hereby
              --------                                                     
purchase from the Company on the date hereof, 1,229 shares of the Company's
common stock ("Common Stock") for $1.00 per share in cash and 997.711 shares of
the Company's Series A Preferred Stock ("Preferred Stock") for $100 per share.
The shares of Common Stock and shares of Preferred Stock purchased pursuant to
this Agreement are collectively the "Shares."  One Thousand (1,000) of the
Shares of Common Stock are subject to vesting (the "Vesting Shares") as set
forth in Section 2, and one-half of the Vesting Shares are Eligible Time
Accelerated Stock ("ETA Stock").

          2.  Vesting of the Shares.
              --------------------- 

          (a) 10% of the Vesting Shares shall become vested as of the last day
of each fiscal year of the Company (the "Fiscal Year End Date") from fiscal 1998
through fiscal 2002 and 16.66% of the Vesting Shares shall become vested as of
the Fiscal Year End Date of each of fiscal 2003, 2004 and 2005, subject to the
earlier vesting of ETA Stock as described below.  All Vesting Shares (in excess
of the Vesting Shares scheduled to vest in any such year) which vests as ETA
Stock under Section 2(b) will reduce in inverse order the Vesting Shares
scheduled to vest, beginning with the Fiscal Year End Date in fiscal 2005.

          (b) Annex A, attached hereto and incorporated herein by reference,
sets forth the vesting provisions and performance criteria (the "Performance
Criteria") for the ETA Stock.  If the Company meets the Performance Criteria for
fiscal 1998, 1999, 2000, 2001 or 2002, 20.00% of the ETA Stock will vest as of
the Fiscal Year End Date of such year.  (For example, if the Performance
Criteria for fiscal 1998 and 1999 were met, but no other Performance Criteria
were met, 40% of the ETA Stock would vest.)

          If the Company does not achieve Plan EBITDA required to vest 100% of
an installment of ETA Stock in any one Performance Year, but in the immediately
following Performance Year the Company's actual EBITDA exceeds Plan EBITDA, the
Company will add the dollar amount by which the Company's EBITDA exceeds Plan
EBITDA in such Performance Year to the Company's EBITDA for the Performance Year
immediately prior thereto and vest the additional ETA Stock that would have
vested in that Performance Year with the addition of the dollar amount carried
back; subject to the limitations set forth elsewhere in this Agreement in the
case of termination of employment and acquisitions of the Company.  Such vesting
for the earlier Performance Year is referred to herein as "Catch Up Vesting."

          (c) Anything in this Agreement to the contrary notwithstanding, if
the Company is acquired by a third party or parties through an asset purchase,
merger or sale of more 

 
than 50% (in value) of the outstanding equity securities of the Company (an
"Acquisition"), (i) all Vesting Shares scheduled to vest pursuant to Section
2(a) in the calendar year in which the Acquisition is closed (and not previously
repurchased by the Company pursuant to Section 3) shall vest immediately prior
to the Acquisition closing date and (ii) if the calendar year in which the
Acquisition is scheduled to close is a Performance Year, all ETA Stock eligible
to vest in such year shall vest immediately prior to the Acquisition closing
date; provided, however, that such ETA Stock shall only vest if Year to Date
      --------  -------
EBITDA as of the Acquisition closing date (or a date reasonably close and prior
thereto) equaled or exceeded 90% of year-to-such-date Plan EBITDA; and provided
                                                                       --------
further that an initial public offering or other issuance of securities by the
- -------
Company shall not constitute an Acquisition.

          (d) You will be entitled to "Catch Up Vesting" (as defined in Annex
A) with respect to all Vesting Shares eligible to vest in a Performance Year
prior to any Performance Year in which an Acquisition is closed if ETA Stock
vested for the year in which the Acquisition is scheduled to close pursuant to
Section 2(c).  Shares of ETA Stock that are eligible for Catch Up Vesting but
that do not vest pursuant to the preceding sentence shall be subject to the
Company's Purchase Option provided in Section 3.  In addition, the Company shall
have the right to purchase pursuant to Section 3 all shares of ETA Stock which
were eligible for accelerated vesting with respect to Performance Years prior to
the calendar year in which the Acquisition is closed which did not so accelerate
pursuant to Section 2(c) or Section 2(b) and Annex A.

          (e) The proceeds of the Acquisition attributable to all unvested
Vesting Shares outstanding on the closing date of the Acquisition (other than
ETA Stock repurchased pursuant to the preceding sentence) (the "Escrowed
Acquisition Proceeds"), will be deposited with the Escrow Agent and will be
distributed to you one year after the Acquisition closing date, but only if you
are then an employee of the Company; provided that if (i) you are terminated at
                                     --------                                  
the time of or after the Acquisition or (ii) you are not offered a job with
commensurate salary and responsibilities by the acquiring entity (or a
subsidiary or parent thereof), then the Escrowed Acquisition Proceeds will be
distributed to you immediately.

          (f) Anything in this Agreement to the contrary notwithstanding, all
unvested Vesting Shares shall vest immediately upon death or disability.
"Disability" means that you are totally physically disabled, as determined in
writing by your personal physician and, at the Company's option, confirmed by a
physician selected by the Company.  You will allow any such physicians to
conduct such physical examinations and tests and to review such of your medical
records as he or they deem appropriate.

          3.  Company Purchase Option.
              ----------------------- 

          (a) If you voluntarily Terminate your Employment prior to December
31, 2002, the Company will have the unconditional right and option to purchase
any or all of your Vesting Shares (whether vested or unvested) for $1.00 per
share and you shall be released from the Covenant Not to Compete pursuant to
Section 4(b).  As used in this Agreement, "Termination of Employment" means the
time when the employee-employer relationship

                                       2

 
between you and the Company is terminated for any reason whatsoever, with or
without cause, whether voluntary or involuntary. In this Agreement in the
context of employment, the term "Company" shall mean a subsidiary or parent of
the Company if you are then employed by such subsidiary or parent. "Terminate
your Employment" has a correlative meaning.

          (b) If there is a Termination of Employment for any reason other than
a voluntary termination, you can choose either to (i) allow the Company the
unconditional right and option to purchase all of your Vesting Shares (whether
vested or unvested) for $1.00 per share and be released from the Covenant Not to
Compete pursuant to Section 4(b) or (ii) keep your Vesting Shares which are
vested and be subject to the Covenant Not to Compete pursuant to Section 4(b),
in which case the Company will have the unconditional right and option to
purchase the unvested Vesting Shares for $1.00 per share.  The Company's right
and option set forth in Sections 3(a), 3(b) and 3(c) is referred to herein as
the "Purchase Option."

          (c) In the event of an Acquisition, the Company may purchase for
$1.00 per share all shares of ETA Stock eligible for accelerated vesting in any
Performance Year prior to the calendar year in which the Acquisition is closed,
which did not accelerate and vest pursuant to Section 2.

          (d) The Purchase Option, if exercised, must be exercised no later
than 60 days after a Termination of Employment, or the Vesting Shares subject
thereto will automatically be deemed vested.  The Purchase Option may be
exercised in whole or in part.  The Purchase Option will be effective when
delivered or mailed and must be exercised in writing and sent to Investor as
provided in Section 12(b) of this Agreement and to the Escrow Agent (as defined
in Section 6 hereof) as provided in the Joint Escrow Instructions.  Amounts due
to you as a result of exercise of the Purchase Option shall be payable in cash
promptly after exercise of the Purchase Option or, in the case of ETA Stock
and/or "Catch Up Vesting," as soon as reasonably practical after determination
of whether or not any applicable Performance Criteria were met.

          4.  Covenant Not To Compete.
              ----------------------- 

          (a) Recitals.  Investor acknowledges and agrees that he has technical
              --------                                                         
expertise associated with the heavy duty truck parts business and related
businesses, all to the extent conducted by the Company as of the date of
termination of employment (the "Business") and is well known in the Business
community throughout the United States.  In addition, Investor has valuable
business contacts with clients and potential clients of the Business and with
professionals in the Business.  Furthermore, Investor's reputation and goodwill
are an integral part of his business success throughout the areas where the
Business is and will be conducted.  If Investor deprives the Company of any of
his goodwill or in any manner uses his reputation and goodwill in competition
with the Company, the Company will be deprived of the benefits it has bargained
for pursuant to this Agreement.  The Company would not have entered into this
Agreement but for Investor's Covenant Not To Compete.

          (b) Covenant Not To Compete.  During your employment by the Company
              -----------------------                                        
and for a period of twelve (12) months thereafter (the "Term"), you will not,
directly or indirectly, own (except through ownership of less than 5% of the
securities of a publicly traded 

                                       3

 
company), manage, join, operate or control, or participate in the ownership,
management, operation or control of, or be connected as a director, officer,
employee, partner, consultant or otherwise with, or permit your name to be used
by or in connection with, any profit or non-profit business or organization
which is engaged in the Business in whole or in part, anywhere in the United
States so long as the Company carries on the Business therein.

          (c) No Solicitation of Customers or Employees.  Investor agrees that:
              -----------------------------------------                        

              (i)   during the Term, Investor shall not, directly or indirectly,
divert or take away (or attempt to do so) from the Company or any affiliate of
the Company (including without limitation by divulging to any competitor or
potential competitor of the Company) any person, firm, corporation or other
entity who is or was a customer of Company or any subsidiary of Company or whose
identity is known to Investor at the date hereof or the date of Termination of
Employment as one whom the Company or any affiliate of the Company intends to
solicit, except in connection with any business endeavor which is not prohibited
by Section 4(b) hereof; and

              (ii)  during the Term, Investor shall not, directly or indirectly,
hire or offer employment to or seek to hire or offer employment (other than
employment with the Company or a subsidiary thereof) to any employee of the
Company or any subsidiary of the Company whose employment is continued by the
Company after the date hereof or any employee of any successor or affiliate of
the Company which is engaged in the Business, unless the Company first
terminates the employment of such employee or the Company gives its written
consent to such employment or offer of employment.

          (d) Severability of Provisions.  In the event that the provisions of
              --------------------------                                      
this Section 4 should ever be adjudicated by a court of competent jurisdiction
to exceed the time or geographic or other limitations permitted by applicable
law, then such provisions shall be deemed reformed to the maximum time or
geographic or other limitations permitted by applicable law, as determined by
such court in such action.  Without limiting the foregoing, the covenants
contained herein shall be construed as separate covenants, covering their
respective subject matters, with respect to (i) each of the separate counties of
the state of California and other places in which Company or any of its
subsidiaries transacts any business, (ii) each business conducted by Company or
any of its subsidiaries, and (iii) the Company and its successors separately.
Each breach of the covenants set forth herein shall give rise to a separate and
independent cause of action.

          (e) Injunctive Relief.  Investor acknowledges that (i) the provisions
              -----------------                                                
of Section 4(b) and 4(c) and Section 9 are reasonable and necessary to protect
the legitimate interests of the Company, and (ii) any violation of Section 4(b)
or 4(c) or Section 9 will result in irreparable injury to the Company, the exact
amount of which will be difficult to ascertain, and that the remedies at law for
any such violation would not be reasonable or adequate compensation to the
Company for such a violation.  Accordingly, you agree that if you violate the
provisions of Section 4(b) or 4(c) or Section 9, in addition to any other remedy
which may be available at law 

                                       4

 
or in equity, the Company shall be entitled to specific performance and
injunctive relief, without posting bond or other security, and without the
necessity of proving actual damages.

          (f) Other Agreement.  The provisions of this Section 4 are in
              ---------------                                          
addition to any Employee Confidentiality Agreement previously executed by you,
which remains in effect.

          5.  No Employment Agreement.  Nothing contained in this Agreement (i)
              -----------------------                                          
obligates the Company, or any subsidiary or parent of the Company, to employ
Investor in any capacity whatsoever, or (ii) prohibits or restricts the Company
(or any such subsidiary or parent) from terminating the employment of Investor
at any time or for any reason whatsoever, with or without cause, and Investor
hereby acknowledges and agrees that neither the Company nor any other person has
made any representations or promises whatsoever to Investor concerning
Investor's employment or continued employment by the Company.

          6.  Escrow of Shares.  As security and to ensure the availability for
              ----------------                                                 
delivery of Vesting Shares in case of an exercise of the Purchase Option,
Investor will deposit with the escrow agent (the "Escrow Agent") named in the
joint escrow instructions attached hereto as Annex B (the "Joint Escrow
Instructions"), certificates representing the Vesting Shares, together with 10
stock assignments duly endorsed in blank, a copy of which is attached hereto as
Annex C.  Such documents are to be held by the Escrow Agent pursuant to the
Joint Escrow Instructions.  In the case of any conflict or inconsistency between
this Section 6 and the Joint Escrow Instructions, the Joint Escrow Instructions
shall control.

          7.  Change in Capitalization.  If from time to time during the term of
              ------------------------                                          
this Agreement there is (i) any stock dividend or stock split or similar event
or (ii) any consolidation, merger or sale of all, or substantially all, of the
assets of the Company in which the consideration receivable by Investor consists
of securities, then in such event any and all new, substituted or additional
securities to which Investor may become entitled by reason of his ownership of
the Shares shall immediately become subject to this Agreement and shall assume
the same status with respect to vesting as the Shares upon which such dividend
was paid or in substitution for which such additional securities were
distributed.  While the total price for all Shares subject to the Purchase
Option shall remain the same after each such event, the price per Share upon
exercise of the Purchase Option shall be appropriately adjusted by the Board of
Directors of the Company.

          8.  Investor Representations and Agreements.  Investor hereby
              ---------------------------------------                  
represents and warrants, and agrees with, the Company as set forth below.

shall be sold, transferred, assigned or pledged (including transfer by operation
of law) and any attempt to make any such sale, transfer, assignment or pledge
shall be null and void and of no effect.  The Company shall not be required (a)

Company or Investor unless approved in writing, and, in the case of the Company,
authorized by its Board of Directors.  The failure at any time to enforce any of

                                    ANNEX A

                           CITY TRUCK HOLDINGS, INC.

                             PERFORMANCE CRITERIA
                             --------------------

          This Annex A sets forth the Performance Criteria, detailed vesting
provisions with respect to the vesting of ETA Stock, which is a part of the
Shares to be acquired by Investor pursuant to the Stock Purchase, Vesting and
Repurchase Agreement dated as of October 19, 1998 among the Company and Investor
(the "Agreement").  Capitalized terms used herein and not defined have the
meanings ascribed to them in the Agreement.

          As stated in Section 2(b) of the Agreement, 20% of the ETA Stock shall
become eligible for vesting as of the end of each fiscal year from fiscal 1998
through fiscal 2002 (each of such full fiscal years being defined in the
Agreement as a Performance Year).

          For each Performance Year, the amount of Eligible ETA Stock that shall
become vested (effective as of the end of the fiscal year) will be determined by
comparing the Company's actual EBITDA (as defined below) as of the end of such
fiscal year (as determined from its audited financial statements) to Plan EBITDA
(as defined below) for such fiscal year.  The percentage of Eligible ETA Stock
that shall become vested at the end of each Performance Year shall be as set
forth in the following table:



                 Actual EBITDA as a %              Percentage of Eligible
                        of Plan                         ETA Stock that
                        EBITDA                       shall become vested
                 --------------------                -------------------
                                                           
                 less than   85.00%                            0%
                             88.75%                           30%
                             92.50%                           60%
                             96.25%                           80%
                               100%                          100%


          Vesting between the percentages listed in the table above will be
linearly interpolated.

          "EBITDA" means, for any fiscal year, consolidated pre-tax income plus
interest expense (including non-cash interest, amortization of original issue
discount and the interest component of capital leases) on indebtedness and
amortization of goodwill, covenants not to compete and similar intangibles, all
as determined in accordance with generally accepted accounting principles and as
reflected in the Company's audited consolidated financial statements.

          "Plan EBITDA" means, for each Performance Year, the dollar amount of
EBITDA set forth in the Operating Plan developed by management and approved by
the Board of Directors.  Plan EBITDA will be adjusted from time to time as may
be mutually agreed upon to reflect the expected contribution to EBITDA of
acquisitions or major corporate projects.

Dear Sir or Madam:

          As the person identified herein as Escrow Agent for City Truck
Holdings, Inc. (the "Company"), a Delaware corporation, and the undersigned
holder of common stock, par value $.01 per share, of the Company (the
"Purchaser"), you are hereby authorized and directed to hold the documents
delivered to you pursuant to the terms of that certain Stock Purchase, Vesting
and Repurchase Agreement (the "Agreement") dated as of October 19, 1998, in
accordance with the following instructions:

          1.  In the event the Company, or any assignee of the Company (referred
to collectively herein as the "Company"), shall elect to exercise the Purchase
Option (as defined and described in the Agreement), the Company shall give to
the Purchaser and you a written notice specifying the number of shares of stock
to be purchased, the purchase price and the time for a closing hereunder at the
principal office of the Company, which time shall not be less than 20 days after
the date of such written notice.  Unless you shall have received written notice
from Purchaser at least five days prior to the date specified for the closing
objecting to consummation of the transaction, Purchaser and the Company hereby
irrevocably authorize and direct you to close the transaction contemplated by
such notice in accordance with the terms of said notice including prompt
delivery of the stock certificate(s) representing the shares purchased.  Any
objecting notice from Purchaser shall set forth in reasonable detail the basis
for his objections, but his failure to do so shall not affect your duties
hereunder.

          2.  At the closing you are directed to (i) date a stock certificate
assignment form or forms necessary for the transfer in question, (ii) fill in
the number of shares being transferred and (iii) deliver same together with the
certificate or certificates evidencing the shares to be transferred to the
Company, against the simultaneous delivery to you of the purchase price for the
number of shares of stock being purchased pursuant to the exercise of the
Purchase Option.  Promptly after the closing, the Company shall deliver to you
any certificate or certificates representing shares which were not so purchased
and remain subject to these Joint Escrow Instructions.

          3.  Purchaser does hereby irrevocably constitute and appoint you as
his attorney-in-fact and agent for the term of this escrow to execute with
respect to such securities all documents necessary or appropriate to make such
securities negotiable and complete any 

                                      B-1


 
transaction herein contemplated, including but not limited to any required
filings with all other governmental or regulatory bodies.

          4.  This escrow shall terminate upon termination of the Purchase
Option with respect to all Common Shares under the Agreement.  Within ten days
after each date of vesting under Sections 2(a) and 2(b) of the Agreement, the
Company shall notify you and Purchaser in writing of the number of shares which
have vested on that date.  Within 20 days after your receipt of such notice, you
shall deliver to Purchaser a certificate or certificates evidencing the shares
which have so vested.  Promptly following any exercise of the Purchase Option,
you shall deliver to Purchaser a certificate or certificates representing the
number of shares of stock not theretofore repurchased by the Company pursuant to
such exercise of the Purchase Option which have vested (less such shares as have
been previously delivered).

          5.  If at the time of termination of this escrow you should have in
your possession any documents, securities or other property belonging to
Purchaser, you shall deliver all of same to Purchaser and shall be discharged
from all further obligations hereunder.  The Company hereby authorizes you at
any time and from time to time after the date hereof to comply with a written
request from Purchaser, a copy of which you shall deliver to the Company, and
unless the Company shall have given you written notice of its objection to such
request within 30 days following its receipt thereof, to deliver to Purchaser a
certificate for that many shares of stock as have become vested in accordance
with the terms of the Agreement (less such shares as have been previously
delivered).

          6.  Your duties hereunder may be altered, amended, modified or revoked
only by a writing by the parties hereto.

          7.  You shall be obligated only for the performance of such duties as
are specifically set forth herein and may rely and shall be protected in acting
or refraining from acting in reliance upon any instrument reasonably believed by
you to be genuine and to have been signed or presented by the proper party or
parties.  You shall not be personally liable for any act you may do or omit to
do hereunder as Escrow Agent or as attorney-in-fact for Purchaser while acting
in good faith and in the exercise of your own good judgment, and any act done or
omitted by you pursuant to the advice of our own independent attorneys shall be
conclusive evidence of such good faith.

          8.  You are hereby expressly authorized to disregard any and all
warnings given by any of the parties hereto or by any other person or
corporation, excepting only orders or process of courts of law, and are hereby
expressly authorized to comply with and obey orders, judgments or decrees or any
court.  If you obey or comply with any such order, judgment or decree of any
court, you shall not be liable to any of the parties hereto or to any other
person, firm or corporation by reason of such obedience or compliance,
notwithstanding any such order, judgment or decree being subsequently reversed,
modified, annulled, set aside vacated or found to have been entered without
jurisdiction.  For purposes of this paragraph 8, an objection made pursuant to
paragraph 1 by the Purchaser shall not be deemed a warning.

                                      B-2


 
          9.  You shall not be liable in any respect on account of the identity,
authority or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder or thereunder.

          10.  You shall be entitled to employ such independent legal counsel
and other experts as you may deem necessary properly to advise in connection
with your obligations hereunder, may rely upon the advice of such counsel and
may pay such counsel reasonable compensation therefor.

          11.  Your responsibilities as Escrow Agent hereunder shall terminate
on the thirtieth day following receipt by the parties of your written notice of
resignation.  In the event of any such termination, the Company shall appoint a
successor Escrow Agent.

          12.  If you reasonably require other or further instruments in
connection with these Joint Escrow Instructions or obligations in respect
hereto, the necessary parties hereto shall join in furnishing such instruments.

          13.  It is understood and agreed that should any dispute arise with
respect to the delivery and/or ownership or right of possession of the
securities held by you hereunder, you are authorized and directed to retain in
your possession without liability to anyone all or any part of said securities
until such dispute shall have been settled either by mutual written agreement of
the parties concerned or by a final order, decree or judgment of a court of
competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you shall be under no duty whatsoever to institute or defend
any such proceedings.

          14.  Any notice required or permitted hereunder shall be given in
writing and shall be deemed effectively given upon personal delivery or upon
deposit in the United States mail, by registered or certified mail with postage
and fees prepaid, addressed to each of the other parties thereunto entitled at
the following addresses, or at such other addresses as a party may designate by
