Purpose and vehicle placement

The offered glass is a factory glazing designed for the rear left side of the body in Mercedes X164 family models. It is a so-called quarter window, mounted in the rear part of the side structure, between the main rear door window and the rear of the body. This placement contributes to:

• better illumination of the rear passenger cabin,
• increased field of view for the driver during maneuvers,
• consistency of the side body line and vehicle aesthetics.

Technical characteristics of the glass

The glass belongs to the group designated as AS3, which in practice means specialized automotive glass with enhanced performance parameters. This type of glazing is designed for:

• adequate mechanical strength in the side area,
• controlled reaction of the glass to damage,
• maintaining required safety standards for passengers. Thanks to the factory fit for the Mercedes X164 body, the glass works with original seals and moldings, which facilitates installation and reduces the risk of leaks.

Benefits of using an original rear side window

Choosing an original rear glazing for a Mercedes X164 provides a number of practical advantages:

• Precise fit – the shape and profile of the glass are consistent with the factory body geometry, which facilitates installation and proper seating in the frame.
• Consistent aesthetics – maintaining a uniform line of windows on the left side of the vehicle, without differences in shade or glass reflections.
• Acoustic comfort – proper sealing limits the penetration of noise from the outside into the rear part of the cabin.
• Structural safety – the glass contributes to the side body structure, supporting the stability of this zone.

Condition of the item and practical application

The offered glass is a used component, which in the case of original Mercedes body parts allows for combining reasonable cost with the preservation of factory build quality. This solution is particularly beneficial for post-accident repairs, replacing damaged glazing, or restoring full functionality to the side body section in older premium class vehicles. If you want to better understand why, in the case of older premium segment cars, original second-hand parts are often a more predictable choice than new replacements, it is worth reading the article The myth of the ideal new part: why is a used factory part the only reasonable choice for older cars?.
