Fitment questions
What years does the Vauxhall Signum cover, and are there different generations to worry about?
The Signum was produced as a single generation from 2003 to 2008, built on the same Z-CAR platform as the Vectra C, and there was a facelift in 2005 that updated some exterior panels. Because the Signum only ever came as a five-door hatchback, there are no body-style variants to separate out, but you should be aware that pre-facelift (2003–2005) and post-facelift (2005–2008) quarter panels may not be interchangeable. Always confirm with the breaker which pressing fits your exact registration.
Will a quarter panel from a 2004 Signum fit my 2006 model?
Your 2004 car is pre-facelift and your 2006 is post-facelift, and the 2005 facelift is a known boundary where exterior pressings can differ on the Signum. It is possible the quarter panel changed at that point, so you should not assume a direct swap across this boundary. Confirm with the breaker by giving them both registrations so they can check the panel profiles match before you commit.
Does the trim level matter when sourcing a Signum quarter panel — for example, does it differ between an Elegance and a Design?
Trim level does not affect quarter panel fitment on the Signum — the shell pressing is the same whether the car is an Elegance, Design, or Vector. What can vary by trim is any moulding, cladding, or feature strip attached to the panel, so a quarter from a different trim may arrive without the exact finishing pieces your car has. The steel panel itself should fit regardless of trim, but factor in cosmetic differences when agreeing a price with the breaker.
Does a Vectra C quarter panel fit a Signum, given they share the same platform?
The Vectra C and Signum share the Z-CAR platform, but the Signum has a distinctly different roofline, C-pillar, and rear body shape compared to the Vectra C estate or hatchback, so the quarter panels are not the same pressing. Whether any specific section of metalwork crosses over between the two models is something you should confirm with the breaker against both registrations rather than assume from the shared platform alone.
Does it matter whether the quarter panel is NS or OS when ordering?
Yes — quarter panels are handed, meaning the nearside (passenger side, left) and offside (driver side, right) are mirror images of each other and are not interchangeable. Always tell the breaker clearly which side you need, and if you are unsure, check which side of the car has the damage before making contact.
Can I use a quarter panel from a Signum with a different engine, for example a diesel instead of a petrol?
Engine choice has no bearing on quarter panel fitment — the body shell is identical regardless of whether the donor car was a diesel or petrol. Focus instead on the model year relative to the 2005 facelift and which side of the car you need, as those are the factors that actually determine whether a panel will fit your vehicle.
