Mercedes W126 S-Class Restoration Guide: Interior & Trim Checklist
The W126 (1979–1991) was Mercedes' flagship S-Class for over a decade — 280S through 560SEL, saloon and the pillarless C126 coupé (560SEC and siblings). It shares the same basic build quality that keeps W123s on the road past 300,000 miles, which means most surviving cars are structurally sound. What gives up first is almost always the interior: sun-baked wood, tired seals, a shift knob worn smooth. Here's what to check and what's actually available to replace it with.
Body Styles
Saloon (W126) — 1979 to 1991, four-door, the common one.
Coupé (C126) — pillarless two-door, badged SEC. Wood trim, door panel handle trim and some seals are specific to the coupé rather than shared with the saloon — check body style before ordering, not just the model.
Wood Trim: What's Actually Available
Like the R107 and W123 before it, W126 dash lacquer crazes and fades with UV exposure — this is the part almost every survivor needs. Full sets exist for both airbag and non-airbag dashboards, since the airbag (introduced partway through production) changes the dash cutout: a walnut set without airbag and a walnut set with airbag. Zebrano is currently only stocked for the non-airbag dash, so it's not a like-for-like swap for the airbag walnut set. Check which dash you have before ordering — retrofitting one set to the wrong cutout doesn't work.
For a more complete refresh, we also stock a 7-piece walnut dashboard center trim set, and RHD-specific walnut trim for right-hand-drive cars.
Cabin Details: Shift Knob, Cup Holder, Console
The shift knob is a cheap, five-minute win: automatic cars take a walnut or zebrano automatic knob, manual cars a walnut manual knob shared with several other classic Mercedes chassis.
The W126 didn't come with a factory cup holder, which is exactly why an aftermarket wood console insert exists — in walnut, zebrano, or (for the C126 coupé specifically) black leather. Match it to whichever wood finish you chose for the dash.
For a full interior overhaul, there's also a combined AC panel, shifter frame, ashtray and shift knob set in walnut, and a walnut burl wood picnic table pair for the front seat backs, a period-correct S-Class touch that's easy to overlook.
Seals and Weatherstrips
The same rule applies here as on any classic Mercedes: a perished seal lets water into places that are expensive to dry out and repair. We stock door weatherstrip and window running channel seals, full 5-piece door and trunk seal sets (also available for the SEL long-wheelbase), and outer window scraper seals.
If the sunroof leaks or sticks, there's a sunroof repair kit covering the mechanism and a matching sliding seal — the same failure pattern as on the W124: check for damp headlining before assuming a bigger problem.
Exterior Trim
The grille moulding is a common target for corrosion and stone chips over 40+ years; we stock a 7-piece aluminum grille moulding trim set and a 6-vertical-plus-1-horizontal bar set, both filed in our Chrome Accessories collection. Also available: replacement bonnet star badge kits and a trunk star badge for cars where the original has gone missing or dulled.
A Sensible Order
- Seals first — door, window and sunroof, before anything cosmetic
- Wood trim — confirm airbag vs non-airbag dash before ordering
- Shift knob and cup holder — quick wins, match the wood finish
- Grille and exterior trim once the interior is settled
Frequently Asked Questions
Do I need to know if my W126 has an airbag before ordering dash trim?
Yes. The airbag dashboard has a different cutout than the pre-airbag dash, and the wood trim sets are moulded to match one or the other.
Did the W126 come with a cup holder from the factory?
No — like most cars of its era, it didn't. The wood console inserts sold today are aftermarket additions designed to fit the existing console without cutting into original trim.
What's the first thing to check on a W126 you're thinking of buying?
Seals and water ingress, the same as any classic Mercedes of this era — check for damp headlining near the sunroof and examine the door and trunk weatherstrips before you look at anything cosmetic.
