Purpose and body fitment

These rear left doors have been designed specifically for the W177 series body, maintaining factory mounting points for hinges, locks, and seals. The placement on the rear left side of the vehicle ensures proper gap geometry, correct fitment against the pillars, and compatibility with original interior trim elements and the side window.

The original construction ensures:

• preservation of the factory lateral body rigidity,
• proper operation of the lock mechanism and door check straps,
• correct routing of seals and trim strips.

Color and paint coating

The doors are finished in Mountain Grey Metallic - 787, a characteristic metallic grey shade used in Mercedes models. The factory paint coating in this color helps reduce the scope of paintwork required during repair, which in many cases shortens service turnaround time and facilitates maintaining visual consistency across the entire side of the vehicle.

The metallic paint structure provides:

• color consistency with other body elements in the same shade,
• an aesthetic surface appearance when properly prepared for installation,
• easier matching during potential local blending.

Component characteristics and service application

As a part from the Doors and door panels category, this component is intended for professional body and paint repairs, particularly following side damage, replacement of corroded panels, or vehicle reconstruction after a collision. The door construction allows for the transfer of equipment from the existing component, such as upholstery, wiring harnesses, or window regulator mechanisms, in accordance with service procedures for the W177 series.

This solution is particularly useful when:

• replacement of the complete rear left door shell is necessary,
• the existing component has extensive mechanical damage,
• local repair is uneconomical or technically difficult.

Component condition and benefits of use

The doors come from a used vehicle, which in service practice often represents a favorable compromise between repair costs and maintaining original structural quality. Using an original body component allows for maintaining the correct side line, fitment to sills and fenders, and proper interaction with factory seals.

The main advantages of using this component include:

• original geometry and fitment with the Mercedes W177 body,
• factory color in the Mountain Grey Metallic - 787 shade,
• suitability for use in professional accident repairs.
