Purpose and body fitment

The presented rear door is designed for installation on the left side of W212 series models, ensuring proper gap geometry, correct window operation, and compatibility with factory hinge and lock mounting points. Thanks to a design consistent with the manufacturer's specifications, side safety parameters and structural rigidity of the body are maintained.

The component belongs to the Doors and door panels group, meaning it is intended for direct integration with factory seals, fittings, and interior equipment, without the need for vehicle structural modifications.

Color and paint layer

The door is finished in Obsidian Black Metallic, characteristic of many Mercedes E-Class W212 generation configurations. The metallic paint coating ensures visual consistency with other body panels in the same shade, which limits the scope of any potential paintwork to minor corrections or polishing to match adjacent elements.

Selecting a door in the correct color is particularly important for repairs where maintaining the factory look of the vehicle and reducing workshop downtime is a priority.

Technical characteristics and installation

As an original Mercedes component, the rear left door for the W212 is prepared to work with factory sub-assemblies such as the lock, hinges, window guides, or wiring harness. The panel's design allows for the transfer of equipment from the previously installed door, which is beneficial for repairs performed using existing interior components.

The condition described as used means the part comes from dismantling, which in practice allows for the preservation of the original geometry and sheet metal structure. Before installation, standard surface verification for signs of wear, preparation of edges for seals, and inspection of mounting points are recommended.

Practical application and benefits of choosing a used part

Choosing a used rear door for a Mercedes W212 is an economically and technically advantageous solution, especially in the case of post-accident repairs, local corrosion corrections, or replacing a panel after parking damage. The original construction ensures proper fitment with the fender, rocker panel, and pillar, which facilitates gap alignment and latch adjustment.

Using original body panels also allows for maintaining the vehicle's stylistic lines, and the Obsidian Black Metallic color helps achieve a consistent visual effect without the need for full painting of the entire side of the car.
