This info was sent to me by Andy at the Sloan Museum and he ask me to post it: This provides collectors with another resource in original documentation for their Buicks. Unfortunately, GM Media Archive has no additional documentation prior to the 1970 model year. GM Media Archive has Buick Invoices available for the 1982 to 2002 model years. Fees are $50.00 per VIN. They also have Chevrolets since 1977, Pontiacs since 1987, Cadillacs since 1980, Oldsmobiles since 1977, and GMC since 1976.
