Q: How can I find out about the past history of my car?
A: If your vehicle was originally sold in Canada, you can request a vehicle report from GM Canada. Call the GM Canada Customer Communications Centre at 800.263.3777 (toll-free within Canada) and ask for Vintage Vehicle Services (VVS). Direct contact information for VVS is below. For a nominal fee ($45CDN as of Nov 1999) you will receive basic information from the original computerized records such as the option by RPO number, date of shipment, and the Canadian dealer number.
