Purpose and fitment

The presented window is designed specifically for the rear left section of the coupe model, ensuring it maintains the correct geometry, bending radius, and character lines typical for this generation of Mercedes. Proper edge fitment facilitates installation in the door frame or fixed side panel, minimizing the risk of leaks and unwanted stress on the glass.

As an item from the Car windows category, the glass works with factory seals, guides, and mounts, which allows for maintaining the original body rigidity and proper operation of opening mechanisms, if the vehicle's construction provides for them.

Glass characteristics and color

Green AS2-type glass is a popular standard in premium cars, combining good light transmission with reduced interior heating. This type of window:

• provides a pleasant, slightly tinted optical effect without excessively limiting visibility,
• supports thermal comfort for passengers in the rear of the cabin,
• maintains visual consistency with other windows featuring the factory green tint.

Thanks to this, the coupe body retains an elegant, uniform look, and the vehicle's side profile remains consistent with the original Mercedes design.

Condition of the item and benefits of choosing a used part

The window comes from the secondary market, which means it is a used part that retains functionality and performance parameters suitable for further use. Choosing such a solution allows for significantly reducing repair costs compared to new components, while maintaining the manufacturer's original specifications.

For many owners of premium cars, the key is combining rational costs with maintaining the factory character of the vehicle. A used rear left side window in the AS2 standard fits into this trend, enabling a technically correct repair without compromises in terms of fitment and appearance.

Safety and structural function

Side windows in a coupe body play an important role in the vehicle's structure – they stabilize the roofline, work with door seals, and influence interior acoustics. Using original glass with the appropriate thickness and light transmission class helps maintain:

• proper rigidity of the side body section,
• correct seal adhesion and reduction of wind noise,
• a safe field of view for the driver and passengers.

Selecting a window consistent with factory specifications is particularly important in premium cars, where the precision of body panel fitment translates into driving comfort and the durability of the entire structure.
