I have the POP to my car and the Dealer Zone is 16-001. This is from Nov/1966 for a 67 GS400. From what I know I believe this is a Buick internal division car or employee car? The POP had this name on it, was thinking maybe some Buick people here might know of them?? D. C. Ferguson 3412 Concord St Flint, MI Thanks for any help Nelson
