cooperatively and proactively with government agencies and consumer
groups toward solutions that both benefit the customer and are
mutually acceptable to both regulators and industry. We maintain the
belief that industry must retain control over how we conduct our
business, and we must be viewed as part of the solution and not part
of the problem. Meetings with state and other government officials
concerned with auto repair and/or consumer protection are conducted.
Feedback from these representatives are brought back to members, and
the program adjusted as needed.
To assure auto repair customers recourse if they were not
satisfied with a repair transaction, the Motorist Assurance Program
offers arbitration through MAP/BBB-CARE in cooperation with the
Council of Better Business Bureaus and individual participating
Bureaus. MAP "piloted" in Indianapolis and Pittsburgh during spring,
1996 - and publicized "roll-outs" in New Jersey, Detroit (MI), Chicago
(IL) and Richmond (VA) were conducted. To put some "teeth" in the
program, and accreditation requirement for shops was initiated. The
requirements are stringent and a self-policing method has been
incorporated which includes the "mystery shopping" of outlets. In
addition, a committee of service providers had been working diligently
developing standards for newspaper, television and Internet
advertising.
We welcome you to join us as we continue our outreach ...

The Motorist Assurance Program was formed in 1992 by forty
(40) companies who were concerned about the image of automotive
service establishments. Today, MAP is an industry-wide association
dedicated to strengthening consumer satisfaction with the automotive
repair industry. MAP's participants represent the majority of the
nation's multi-bay retail automotive outlets, their parts and
equipment suppliers, independent repair shops, industry associations,
car companies, manufacturers representatives, and the trade press. MAP
is developing standards of service, uniform inspection procedures and
other programs to assure consumers of the industry's professionalism
and the commitment to excellence shared by MAP's sponsoring companies.
MAP's achievements to date include production and
distribution (over 280,000) of the consumer brochure "How to Find Your
Way Under the Hood and Around Your Car", development of a Pledge of
Satisfaction to Consumers and Standards of Service and establishment
of relationships with regulatory agencies.
As auto repair becomes an issue for federal and state
regulators, MAP is working to educate government leaders on the
dynamics of automotive service and the self-monitoring efforts MAP
has undertaken on the industry's behalf. MAP's sponsoring companies
are becoming well-known to government representatives as exemplary
