Used Vauxhall Vectra Sill

No — the Vectra B (1995–2002) and Vectra C (2002–2008) are completely different generations with different bodyshells, so their sills are not interchangeable. Always source a sill from the correct generation to have any chance of a good fit.

Yes, body style is the first thing to get right — the Vectra C was sold as a hatchback, saloon, and estate, and the sill pressings differ between these body styles. Tell your breaker exactly which body style you have before agreeing on a part.

The Vectra C ran from 2002 to 2008 and received a facelift in 2005, but whether the sill pressing changed between the two phases is not something we can state with certainty. Name the boundary to your breaker and ask them to check the part against your exact registration before buying.

Trim level — whether Expression, Design, SRi, or GSi — does not affect sill fitment on the Vectra; the structural sill is determined by generation and body style, not trim. Bear in mind that higher trims may have had different side skirt or body-kit styling fitted over the sill, so the underlying panel should swap across, but the finishing pieces may look different.

The Vectra B estate (1996–2002) has a longer roofline and different rear bodywork compared with the hatchback and saloon, and the sill length and pressing are likely to differ as a result. Stick to sourcing a sill from the same body style — Vectra B estate to Vectra B estate — and confirm the match with your breaker against your registration.

No — the sill is a structural body panel and is the same regardless of whether your Vectra has a petrol, diesel, or any particular engine size. Focus on getting the generation and body style right, and ignore engine variants when searching for this part.
