Cheap Vauxhall Signum Rear Panel

The Signum was produced from 2003 to 2008 as a single generation, based on the Vectra C platform, and all Signums share the same five-door hatchback body style throughout that run. Because there were no generation changes, a rear panel from a 2003 car is likely to be from the same pressing as one from a 2008 car, but mid-production pressing changes can occasionally occur, so always confirm the exact year of the donor car with the breaker against your registration before buying.

The Signum sits on the same platform as the Vectra C, but the Signum is a five-door hatchback with its own distinct rear bodywork, while the Vectra C was offered as a saloon, hatchback, and estate — all with different rear panels. A Vectra C rear panel will not be a straight swap for a Signum, so you need to source a panel specifically listed for the Signum rather than the broader Vectra C family.

Trim level — whether Design, Elegance, or Elite — does not affect the pressing or fitment of the rear panel on the Signum. However, you may find cosmetic differences such as badging locations or rear bumper finish that vary between trim grades, so bear that in mind when matching appearance. The structural panel itself should be the same across all trims.

The Signum received a facelift in 2005, which updated exterior styling including the rear end. While both pre-facelift (2003–2005) and post-facelift (2005–2008) cars share the same generation and platform, whether the rear panel pressing changed at the facelift is not something that can be stated with certainty. You should confirm with the breaker whether the donor panel is from the same facelift phase as your car by checking both registrations before purchasing.

The Signum was only produced as a five-door hatchback; no estate variant was offered under the Signum name. If a seller is listing a Signum estate rear panel, treat that with caution, as they may be confusing it with the Vectra C estate, which has completely different rear bodywork that will not fit your Signum.

A full rear panel on the Signum spans the width of the car and is not a nearside or offside specific part, so side designation does not apply when sourcing this panel. What does matter is confirming the year of the donor vehicle to ensure it matches your own car's production phase, and always cross-reference the breaker's listing against your registration to be sure.
