Terry, if you haven't done so already, send the linked form below to the SAAQ, Quebec's DMV. They will provide you with a Vehicle History Report that shows, besides basic vehicle data, the number of times and dates that the vehicle was registered in Quebec. Because of privacy laws, it no longer shows individual owner's names, however it will show commercial owner's names. It costs $12.25 Canadian dollars and has a three week turnaround time. You can fill out the form on-screen then print it out and mail it. On another note, do you have the dealer name plate? If you do, could you post a photo. I would love to see it. I grew up about three blocks from Park Avenue Chevrolet and spent countless hours there checking out the new cars. Joe.
