Purpose and fitment

The presented rear right door is structurally prepared for installation in Mercedes W177 series models, positioned on the passenger side at the rear. The original design ensures proper alignment with the body line, sills, pillars, and factory seals, which facilitates maintaining cabin tightness and the correct operation of locks and hinges.

Technical characteristics of the component

The door belongs to the Doors and door panels group, meaning it serves both a structural and protective function for the side of the body. The panel has been factory-prepared to work with original mounts, window guides, wiring harnesses, and interior trim elements intended for this body generation.

The Kosmos Black Metallic color (paint code 191) is a dark, metallic shade that blends well with the Mercedes styling line and allows for an aesthetic repair without the need for a full repaint of the entire side of the vehicle, provided the other elements are in the same color. The metallic paint coating promotes even light distribution across the surface, which improves visual consistency with the remaining panels.

Condition and benefits of using a used component

The item is in used condition, which in practice means it comes from dismantling and may show signs of wear typical for this class of parts. However, using original, used doors allows for maintaining factory sheet metal quality, proper structural rigidity, and compatibility with the vehicle's production line, while reducing repair costs compared to new body panels.

For body and paint shops as well as individual users, this is a solution that enables a technically correct reconstruction of the side of the body, while maintaining safety parameters and compatibility with original Mercedes components.

Application in body repairs

The rear right door for the Mercedes W177 is suitable for both post-accident repairs and the replacement of a corroded or mechanically damaged element. Thanks to the factory mounting points, it is possible to use standard assembly procedures, which facilitates work for services specializing in the Mercedes brand and speeds up the process of restoring the vehicle to full operational efficiency.

Replacing the complete door panel is often more technologically predictable than extensive straightening and filling, as it allows for limiting the amount of bodywork and focusing on precise fitting and potential paint corrections.
