Purpose and body fitment

The presented item is designed as a complete front door for the left side, dedicated to installation in the side body zone of the Mercedes W177 model. The construction corresponds to the factory mounting points for hinges, locks, and seals, which facilitates the transfer of equipment from the existing door and allows for maintaining the original body geometry.

The placement in the vehicle on the driver's side facilitates precise alignment with the fender, rocker panel, and pillar, which is significant for both aesthetics and proper closing and cabin tightness. This type of OEM component is particularly recommended for repairs where maintaining factory gaps and body lines is crucial.

Paint finish and Kosmos Black Metallic color

The door is finished in Kosmos Black Metallic - 191, characteristic of many Mercedes W177 configurations. The metallic black provides an elegant, understated look while working well with paint correction and potential shade matching to other body elements.

This type of finish is beneficial for repairs as it allows for limiting the scope of painting to the necessary minimum or preparing the surface for full painting in accordance with the manufacturer's technology. The metallic color masks minor shade differences well after professional polishing and blending.

Technical characteristics and installation

The door belongs to the Doors and door panels group, meaning it is a structural element of the side body, responsible for passenger protection, body rigidity, and proper window and seal operation. The construction is prepared for the transfer of factory equipment, such as the lock, hinges, wiring harness, or upholstery, in accordance with the specific vehicle configuration.

The properly selected weight of the component promotes the correct operation of the hinges and lock, which translates into user comfort – even closing, lack of excessive stress, and stable seating in the body frame. Using the original door panel also facilitates subsequent alignment of the door in the plane with adjacent panels during adjustment in the workshop.

Used condition and advantages of OEM parts

The item is offered in used condition, which in the case of original body doors often represents a favorable compromise between repair cost and maintaining factory quality. A used OEM part retains its original geometry, making the assembly and adjustment process usually less time-consuming than in the case of many aftermarket replacements.
