Cheap Vauxhall Signum Rear Tailgate

The Signum was produced from 2003 to 2008 as a single generation, based on the GM Z-C/epsilon platform, and all cars share the same five-door hatchback body style throughout that run. In broad terms, tailgates from within that 2003–2008 production window are your starting point, but Vauxhall did make minor pressing and trim changes during the model's life, so confirm the exact donor car's registration against yours with the breaker before buying.

The Signum received a facelift in 2005, and while the underlying body structure remained the same, there were styling updates to the rear that may have affected panel pressing details around the tailgate aperture and glass. You should name the 2005 facelift boundary clearly to your breaker and ask them to verify the part against your specific registration, as crossing that boundary is exactly where panel differences are most likely to matter.

No — although the Signum shares its platform with the Vectra C, the Signum has a distinctly different roofline and fastback hatchback body style, so the tailgates are not the same pressings and will not interchange. Always source a tailgate specifically listed for the Signum rather than the Vectra C.

Trim level — whether your car is a Design, Elite, or any other grade — does not affect tailgate fitment; the shell pressing is the same across all Signum trims. You may find cosmetic differences such as varying badging, spoiler fitment, or rear wiper configurations depending on the donor car's spec, so check those details with the breaker if they matter to you, but the tailgate itself will physically fit regardless of trim.

No — engine and gearbox choice have no bearing whatsoever on tailgate fitment for the Signum. Focus only on the body style (five-door hatchback, which is the only style the Signum was sold in the UK) and the model year relative to the 2005 facelift when speaking to a breaker.

Give the breaker your full registration number and let them verify the exact year and specification against their donor vehicle, particularly noting whether your car is pre- or post-2005 facelift. You do not need to mention engine or trim level, but do flag any factory-fit features visible on your tailgate such as a spoiler, privacy glass, or rear wiper, as these may vary between donor cars and affect how well the used part matches your vehicle.
