Cadillac narrows list of ad agency candidates to 6

NEW YORK — General Motors Co. said today it narrowed down its list of candidates to handle advertising for Cadillac to six agencies, a month after announcing it was dumping the luxury brand’s longtime ad partner.

The Detroit automaker said it will hold visits with the candidates in Detroit before Thanksgiving, with finalists making presentations to company executives in January. Cadillac spokesman Nick Twork declined to comment on whether the company has a deadline for making a final pick.
