I'm trying to find someone who has a Caddy or Olds bought from Hartigan Oldsmobile-Cadillac in Park Ridge, between 1964 to 1987.
I need to know Hartigan's Dealer Code! Dealership was sold to Napleton Cadillac and vacant building still exists on the corner of N. Northwest Hwy. and Meacham Avenue.
Someone MUST have this info... :eek:
