Regarding merging MARC and MAFCA, from 1952 - 57 there was one club - MARC. Included within MARC was the Southern California Region of MARC. For what ever reason this region left MARC and formed MAFCA in 1957.
Further MARC and MAFCA are NOT nonprofit charitable corporations.
MAFFI could never merge with MARC and/or MAFCA and maintain their IRS tax status i.e., they are a nonprofit charitable corporation.
Per the MAFFI web site:
SECTION 1. Said corporation is organized exclusively for charitable and educational purposes, including for such purposes the making of distributions to organizations that qualify as exempt organizations under Section 501(c)(3) of the Internal Revenue Code, or corresponding section of future Federal Tax Codes.
SECTION 2. The purpose of this corporation is to preserve the historical significance of the Model A Ford automobile through: the establishment of a museum for vehicles and accessories; shows and exhibitions; education of the general public on that era of transportation history; and the exchange of ideas and information among members, the public and admirers of the Model A Ford to aid in their efforts to restore and preserve the car in its original likeness.
SECTION 3. The trustees may receive and accept on behalf of the Foundation, property, whether real, personal, or mixed, by way of gift, bequest, or devise, from any person, firm, trust, or corporation, to be held, administered, and disposed of in accordance with and pursuant to the provisions of this document; but no gift, bequest or devise of any property shall be received and accepted if conditioned or limited in such manner as to require the disposition of the income or its principal to any person or organization other than a "charitable organization" or for other than "charitable purposes" within the meaning of such terms as defined in this document, or as shall in the opinion of the trustees, jeopardize the Federal Income Tax exemption of this trust pursuant to Section 501(c)(3) of the Internal Revenue Code.
