Purpose and fitment for BMW 3 Series G20/G21

The offered item is a complete rear right exterior door dedicated to the BMW 3 Series generation G20 (sedan) and G21 (Touring estate). Its placement in the rear section, on the passenger side, ensures compatibility with the factory body structure and proper edge alignment relative to the fender, rocker panel, and B-pillar.

As a part originating from the same model line, the door retains the original stampings, sheet metal bending radii, and mounting points for hinges and the lock, which facilitates installation and reduces the need for additional bodywork modifications.

Portimao Blue Metallic – C31 color and aesthetic values

The factory Portimao Blue Metallic – C31 paint is a distinctive, dynamic shade of blue used in modern BMW models, particularly valued in configurations with a sporty character. Using the original metallic coating often allows for limiting the scope of paintwork to just potential shade matching, without the need for a full repaint of the component.

For users concerned about the visual consistency of the bodywork, this means:

• maintaining a uniform color line along the entire right side of the vehicle,
• better matching of the paint structure and gloss to the remaining panels,
• a more professional final result after collision repairs or replacement of corroded doors.

Technical characteristics and installation

The door belongs to the Doors and door panels group, which means it is designed as a load-bearing side body panel that works in conjunction with hinges, the lock, and door opening seals. Its placement in the rear right part of the vehicle requires maintaining proper geometry to ensure:

• correct closing and lock operation,
• even gaps relative to adjacent elements,
• proper seal adhesion to limit noise and water ingress.

As a used component, the door is a practical solution for post-accident repairs when the priority is to combine correct functionality with a reasonable cost of the entire service operation.

Practical application and benefits of choosing original doors

Choosing an original rear right door for the BMW G20/G21 in Portimao Blue Metallic – C31 is a beneficial solution for body shops and individual users who expect:

• factory fitment to the BMW body structure,
• preservation of the characteristic 3 Series styling line,
• reduction of paintwork scope thanks to the original color.

The component will work well both for post-collision repairs and for replacing doors due to operational damage or corrosion, allowing for the restoration of the aesthetics and functionality of the side body section.
