Purpose and fitment

The presented item is a rear left door dedicated to the BMW 1 Series E87/E87N generation, prepared for installation in the rear part of the body on the driver's side. The construction is based on the factory BMW design, which facilitates the transfer of all components from the previous door, such as upholstery, locks, or windows, while maintaining the correct body line.

The original panel geometry ensures proper fitment with the fender, rocker panel, and pillar, which is important for both aesthetics and the tightness and performance of the seals. As a result, this part works well for accident repairs, corrosion corrections, or replacing damaged panels.

Color and paint finish

The door is in the color Quarzblau Metallic – A18, which is a characteristic metallic shade of blue used by BMW at the factory. The metallic paint coating allows for an aesthetic match to a body of the same color, often limiting the scope of additional paint work to polishing or local touch-ups, depending on the condition of the specific unit.

The factory paint structure promotes a consistent light reflection along the entire side of the vehicle, which is essential for precise body and paint repairs. For workshops, this means it is easier to achieve a uniform visual effect across the entire side surface.

Characteristics of the used part

The door comes from disassembly, which means it is a used part that retains the original sheet metal structure and factory stampings. This type of component is particularly valued in repairs where it is important to maintain compliance with factory mounting points for hinges, locks, and window guides.

A used body part is also a cost-effective solution – it allows for reduced expenses while maintaining the original build quality characteristic of BMW. In practice, this facilitates quick installation and reduces the vehicle's downtime in the workshop.

Application in body repairs

The rear left door in Quarzblau Metallic A18 will prove useful in many service scenarios, including:

• accident repairs involving damage to the side of the body,
• replacing corroded or deformed panels,
• restoring the vehicle's original appearance after unprofessional repairs,
• restoration projects where color consistency and factory stampings are important.

Thanks to the original door construction, it is possible to maintain the proper operation of the lock, hinges, and seals after proper installation and adjustment, which translates into comfort of use and a reduction in noise and air drafts.
