Purpose and fitment

The presented door card has been designed specifically for the W166 series body, intended for the rear left side of the vehicle. The precise shaping of the panel guarantees proper adhesion to the door structure, which translates into stable mounting and the absence of unwanted play during operation.

The item is part of the Door panels group, making it fit perfectly into the factory interior architecture while preserving the original lines of the armrest, handles, and contours characteristic of this generation of the Mercedes SUV.

Material and finish

The panel is finished in black, which facilitates integration with most interior configurations used in the W166. The black leather used creates a cohesive, understated, and elegant cabin character, blending well with both light and dark cockpit elements.

The surface structure has been developed with daily use in mind – smooth zones make it easy to keep clean, and the carefully selected texture limits the visibility of minor signs of wear. As a result, the upholstery retains an aesthetic appearance even with intensive use of the rear seat.

Function in interior ergonomics

The door card trim plays an important role in the comfortable operation of the rear passenger area. Properly contoured surfaces allow for comfortable arm support, and the well-thought-out layout of contours and edges improves the perceived space in the hip and shoulder area for passengers.

The panel also serves as a masking layer for internal door mechanisms, such as window guides or electrical harnesses, which contributes to noise reduction and protects these components from accidental damage from the cabin side.

Characteristics of the used part

As a used item, the door card offers a favorable compromise between cost and maintaining the manufacturer's original specifications. This allows for an economical repair or refreshment of the interior without the need to resort to replacements with uncertain fitment. Natural signs of wear are typical for this type of part, yet they do not affect its mounting functionality.

Choosing original upholstery from the secondary market is particularly beneficial in the case of local repairs after mechanical damage or during partial interior restoration, when maintaining the consistency of materials and shades throughout the cabin is a priority.
