Mercedes-Benz SL Sill Replacement Parts

The SL has gone through several distinct generations, each with a different body structure: the R107 (1971–1989), R129 (1989–2001), R230 (2001–2012), R231 (2012–2020), and R232 (2020–present). Sills are body-specific pressing, so you must match the correct generation — a sill from an R230 will not fit an R231. Always tell the breaker your exact year and registration so they can pull the right shell.

No — the sill is a structural body panel and is the same regardless of whether your SL has a six-cylinder, V8, or V12 engine under the bonnet. Engine choice has no bearing on sill fitment, so you don't need to specify your engine when searching. Just focus on matching the correct generation to your car.

Those two cars sit in different generations — the 2008 is an R230 and the 2013 is an R231 — so the sills are not interchangeable. The body structures were redesigned between these generations, meaning the pressing, mounting points, and dimensions will differ. You'll need a sill specifically from an R231 for a 2013 car.

Trim and engine variants do not affect the sill panel itself — the underlying body structure is shared across SL 350, SL 500, SL 55, SL 63, and other derivatives within the same generation. You may find cosmetic differences such as side skirt styling on AMG models, but the structural sill beneath is the same. Be aware that AMG-spec side skirts or sill covers are separate trim pieces and won't match non-AMG ones, so confirm with the breaker what exactly is included in what they're selling.

The R230 ran from 2001 to 2012 and received a facelift around 2008, and while the core sill structure is generally consistent across the generation, minor panel or pressing changes between early and late cars cannot be ruled out. This is exactly the kind of detail you should confirm with the breaker by quoting your full registration, as they can check the specific part against your car's build details. Never assume fitment across a facelift boundary without that check.

Yes — the SL has always been a two-door roadster/convertible, which means its sills are unique to that body style and share nothing with saloon, estate, or coupe variants from other Mercedes ranges. Even within the broader Mercedes family, you cannot substitute a sill from a C-Class or E-Class. Always make clear to the breaker that you need an SL-specific sill for the correct generation of your car.
