Purpose and fitment

The offered item is a complete rear door for the right side, dedicated to the Mercedes C-Class W203 generation body. The construction is based on the manufacturer's factory design, which translates into correct alignment with the rocker panel, pillar, and roofline, as well as compatibility with factory hinges and locks.

Placement in the rear, right part of the vehicle allows for precise replacement of a damaged component without the need for interference with the body geometry. This solution is particularly beneficial for post-accident repairs, corrosion corrections, or restoring the vehicle to its factory specification.

Structural characteristics

The door belongs to the Doors and door panels category, meaning it is a key element of the side skin, responsible for both passenger protection and the rigidity of the side body section. The construction is designed to work with factory seals, glass, locks, and the electrical installation intended for this model.

The component has been designed to maintain proper edge geometry, which facilitates the adjustment of gaps between the door and the fender, rocker panel, and pillar. As a result, after proper installation, it is possible to achieve uniform technological gaps, which is important for both aesthetic and functional reasons (tightness, reduction of wind noise).

Paint finish

The door is finished in Tanzanite Blue Metallic, characteristic of the Mercedes paint palette. The metallic coating ensures visual consistency with a body in the same shade, which significantly limits the scope of any potential paint work after installation.

In practice, this means the possibility of:

• using the component as a base for local shade matching,
• reducing the scope of filling and priming,
• preserving the original paint structure over a large surface of the door.

Use in body repairs

The rear right door on a Mercedes C-Class W203 is often replaced after side collisions, parking damage, or advanced corrosion of the lower edges. Using an original component from the same body generation allows for:

• restoring the correct geometry of the side part of the vehicle,
• maintaining factory hinge and lock mounting points,
• easier fitting of seals and windows,
• reducing the time required for fitting and adjustment.

For body and paint shops, this means a more predictable assembly process, and for the user – a solid base for a durable repair.

Condition and benefits of choosing a used component

The offered product has the status of a used body component, which in practice allows combining a reasonable repair cost with maintaining the manufacturer's original construction. Compared to non-factory replacements, OEM doors provide better fitment to the bodywork and greater predictability in terms of assembly and adjustment.

Choosing a used door is particularly beneficial when the priority is the technical correctness of the repair while simultaneously optimizing the budget allocated for rebuilding the vehicle after mechanical or corrosion damage.
