DEALER MATERIAL
If your dealership has vehicles involved in this campaign, you will receive the following items:
-
List of all vehicles involved in their campaign shipped to your dealership.
-
One (1) campaign identification label per vehicle involved.
Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle
Identification Number, Owner Names and Address Data, and are furnished to the involved dealers with the campaign bulletin. Owner name and address
data furnished will enable dealers to follow-up with owners involved in this campaign.
These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle
registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing for the follow-up
necessary to complete this campaign.
TRANSFER OF VEHICLE
If a vehicle has been transferred or sold to another location, please forward Campaign Identification Label and vehicle information for this vehicle to
your Buick Zone Office for handling with the proper dealer.
CHANGE OF OWNER INFORMATION
Dealers are to use the Dealer Communication System (D.C.S.) to provide Buick Motor Division with subsequent Buick Owner Information. By reporting
a change of owner name or address of a vehicle in Campaign status over the D.C.S., the need to send in an S-866 Form for that vehicle is eliminated.
Terminal input instructions are covered in the D.C.S. Manual under Section 9, Page 9-J01A and B.
OWNER NOTIFICATION
Owners of vehicles involved in this campaign will be notified by Buick Motor Division (see copy of owner letter included with this Bulletin).
