Purpose and fitment for BMW 3 Series E90/E91

The offered item is a complete door shell designed for the front left side of four-door BMW 3 Series E90/E91 models. Thanks to its factory origin, compatibility with the body line, creases, and the geometry of pillars and sills is maintained, which facilitates proper gap alignment and minimizes the need for additional bodywork.

The placement on the vehicle is clearly defined as the front driver's side, which helps avoid errors when selecting parts and speeds up the repair or replacement process of the damaged component.

Characteristics of the Black Sapphire Metallic - 475 paint

The door is finished in the original BMW Black Sapphire Metallic - 475 color, which is a dark, metallic black with a deep, modern character. This type of paint effectively masks minor dirt while highlighting the side profile of the body, which is particularly important in the dynamically styled 3 Series.

The metallic structure of the paint coating ensures visual consistency with other body elements in the same color code, which limits the scope of any potential paintwork to a minimum or allows it to be avoided entirely if the condition of the coating is acceptable in the context of the rest of the body.

Performance parameters and assembly aspects

The door belongs to a group of structural elements of significant importance for the lateral rigidity of the body, which is why using an original BMW component helps maintain the correct body geometry. The weight of the element indicated in the specification points to a full-scale steel construction, typical for this generation of the 3 Series, which is important for both safety and the proper operation of hinges and locks.

As a part from the Doors and door panels category, the element is prepared for further configuration with equipment specific to a given vehicle (window, lock, wiring, seals – according to the car's equipment). Using an original shell facilitates the installation of factory components without the need for modifications.

Used condition and economic benefits

The item is offered as a used part, which allows for a significant reduction in repair costs compared to new body components, while maintaining factory origin. In practice, this means a favorable compromise between price and quality, especially in the case of post-accident repairs or the renovation of a vehicle used on a daily basis.
