1. Under the Hood: Open the hood of your Vectra and look on the driver's side near the windshield. You should find a metal plate with the VIN stamped on it.
2. Driver's Side Door Pillar: Open the driver's side door and look at the door pillar (the vertical frame between the door and the windshield). The VIN should be stamped on a metal plate near the bottom of the pillar.
3. Vehicle Registration Documents: The VIN should also be listed on your vehicle registration documents, such as the title and registration.
4. Underneath the Rear Bumper: In certain models, the VIN may be located underneath the rear bumper. Inspect this area for a sticker containing the VIN.
Additionally, you can obtain the VIN by running a vehicle history report or by contacting your local Vauxhall dealership with your vehicle's details.
