Restoring classic car body & interior parts often comes down to one decision: should you pay for an original control with the right period details, or choose a less specific replacement? For a 1955 Oldsmobile or Buick project, the 1955 Oldsmobile Buick 4-Way Power Seat Switch OEM GM Classic Car Interior is aimed squarely at that choice.
Quick verdict
At $190, this is a specialized restoration component rather than a casual upgrade. Its strongest appeal is the combination of an original vintage OEM GM assembly, a stated 1955 Oldsmobile and Buick application, and a factory-correct mounting and terminal layout. The compromise is equally clear: it is used, unrestored, and shows standard aging and surface wear.
1955 Oldsmobile Buick 4-Way Power Seat Switch OEM GM Classic Car Interior

The main reason to choose this switch is authenticity. It is described as an original OEM GM 4-way power seat switch assembly with the correct oval mounting flange and 5-pin terminal configuration, details that matter when a classic car restoration interior needs to retain its original character. The assembly is also positioned for a period-correct restoration, hot rod build, or direct replacement project.
The limitation is its condition. This is not presented as a refinished or restored control; vintage wear and surface aging are part of the purchase. The $190 price therefore makes the part most sensible for a project where an original component and its specific mounting layout matter more than a fresh appearance.
Who it suits
This switch fits the priorities of an owner working on a 1955 Oldsmobile or Buick interior who wants an original-style power-seat control instead of a generic-looking substitute. It may also suit a hot rod builder whose design calls for a vintage GM interior component and the listed four-way function.
It is less compelling for a shopper seeking a cosmetically renewed piece. The stated application and terminal arrangement also make it a focused restoration choice, so the vehicle and wiring plan should align with those details before the purchase decision is made.
What stands out from the listed details
The oval mounting flange gives the part a specific physical identity, while the 5-pin configuration identifies the electrical layout. Together with the OEM GM designation, those details make the switch more useful for a restoration guided by original equipment specifications than for an open-ended interior refresh.
Meaningful trade-offs
Originality comes with visible age here. Surface wear may be acceptable-or even appropriate-for a driver that retains its vintage character, but it could require cosmetic work in a highly finished dashboard or upholstery project. The $190 asking price also reflects a component with a narrow, vehicle-specific role rather than a broad interior accessory.
Bottom line
Choose the 1955 Oldsmobile Buick 4-Way Power Seat Switch when original OEM GM character, the oval flange, and the 5-pin layout match your restoration plan. Pass on it if unrestored condition conflicts with the look you want from your classic car interior.
