Purpose and fitment

The presented item is designed as a complete front left door for the W177 series body, with precise placement on the driver's side front of the vehicle. By maintaining factory geometry and mounting points, the part ensures proper alignment with the fender, rocker panel, pillar, and seals, which facilitates installation and reduces the need for additional bodywork adjustments.

Color and body finish

The door is finished in the Kosmos Black Metallic shade, characteristic of many equipment configurations for this generation. The metallic black provides an aesthetic, understated look and blends well with both light and dark styling packages. Using original paint in the same color code helps minimize the scope of paintwork required and makes it easier to achieve a uniform surface with the remaining body panels.

Technical and structural characteristics

The door belongs to the Doors and door panels group, meaning it is a key element of the vehicle's side structure, responsible for rigidity, proper window operation, and correct seal adhesion. The construction is intended for use with factory hinges, locks, door wiring harnesses, and other components mounted in this area. The weight of the element specified in the documentation confirms the use of the appropriate sheet metal thickness and reinforcements, which is important for both safety and interior acoustics.

Condition and service application

The offered item is a used part, making it an attractive service solution for post-accident repairs, bodywork corrections, or replacing damaged doors. Choosing an original component from disassembly allows for maintaining factory fitment parameters while optimizing costs compared to purchasing a new body panel.

Application in repairs and upgrades

The door is suitable for both standard replacement of a damaged element and more extensive bodywork, including gap adjustment, restoring the factory side line, or improving the vehicle's appearance after a collision. Thanks to the preservation of the original construction, it is possible to use existing sub-assemblies mounted in the door, such as fittings, seals, or equipment elements, in accordance with the configuration of the specific vehicle.
