Specifically, these items:
Members have a general duty of integrity, honor and fair dealings toward the general public.
Members shall employ truth and accuracy in advertising and selling.
Members shall expose or halt, where found, any scheme designed to deceive or defraud
the automobile buying public and aid in prosecuting those guilty of such acts.
