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.

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.
