Purpose and body fitment

The presented molding is a component designed for the rear left side of the body, in the area of the quarter window on the Mercedes B-Class W245 generation. The design has been engineered to accurately replicate factory body lines, which facilitates installation and helps maintain the original geometry of the glazing. Its placement on the driver's side makes this element both visually and functionally significant – it seals the window outline and contributes to the tightness of the connection.

Color and Kosmos Black Metallic finish

The molding is finished in the Kosmos Black Metallic shade, characteristic of many Mercedes paint configurations. The metallic structure of the coating ensures consistency with the factory body paint while effectively masking minor dirt and typical signs of wear. As a result, the element harmoniously blends into the vehicle's side profile without the need for additional painting when matching the original color.

Protective and aesthetic function

As part of the Protective and decorative moldings group, this trim serves a dual role:

• it supports the stable seating of the glass in the rear left section of the body,
• it masks edges and structural joints, improving the visual continuity of the side line.

Such a solution reduces the risk of contaminants entering the seal area and helps maintain an orderly appearance of the rear quarter window zone, which is particularly important after body repairs or glass replacement.

Characteristics of the used part

The item comes from a used vehicle, which in practice means it may show standard signs of wear typical for original body parts. The advantage of such a solution is the preservation of factory fitment for the Mercedes B-Class W245 model, which facilitates installation and helps avoid issues with geometry or alignment often encountered with lower-quality aftermarket replacements.
