Purpose and compatibility

The offered item is a complete rear left door designed for the BMW 1 Series E87/E87N generation. Its placement on the rear driver's side of the vehicle allows for a direct replacement of damaged bodywork in this area, while retaining factory hinge mounting points, locks, and seals.

The original origin of the door ensures compatibility with the factory BMW body construction, which facilitates installation and reduces the need for additional bodywork adjustments.

Color and paint layer

The door comes in Nautikblau Uni – A21, a color characteristic of selected BMW 1 Series E87/E87N configurations. The uniform, non-metallic "Uni" paint coating provides a solid base both for keeping the current color and for potential repainting during major body repairs.

Maintaining the original shade makes it easier to match the color with other body components, which is crucial for spot repairs and minimizing visual differences between panels.

Structural characteristics

The door belongs to the Doors and door panels group, meaning it acts as a load-bearing element of the side body, responsible for proper window operation, cabin sealing, and interaction with the lock and seals. The structure is prepared for the installation of factory internal components, such as upholstery, window mechanisms, or locks.

The original geometry of the edges and creases allows for proper alignment with the rear fender, B-pillar, and rocker panel, which is important for both aesthetics and the correct closing of the door and seal performance.

Condition and service application

The item is used, making it a practical solution for accident repairs where the priority is to maintain the original body structure on a reasonable budget. This type of door works well for:

• repairs after side collisions,
• body restorations in older BMW 1 Series vehicles,
• projects restoring the car to factory condition after localized damage.

Using an original body part reduces the risk of issues with body lines, panel gaps, and the operation of locks and seals.

Benefits of using original BMW doors

Using factory rear left doors for the BMW 1 Series E87/E87N provides several significant service benefits:

• Factory fit – maintaining original body geometry and mounting points.
• Visual consistency – the Nautikblau Uni A21 color makes it easier to match with the existing paintwork.
• Repair cost optimization – a used body part often helps reduce the scope of body and paint work.

As a result, this product is a functional solution for both body shops and individual users who care about the technical condition of their BMW.
