Purpose and vehicle placement

The presented glass is designed for installation in the rear left part of the body, in the side quarter area. This placement is important for both structural rigidity and proper interior illumination as well as passenger visibility. Dedicated fitment for the specific Mercedes model reduces the risk of leaks, stress, and improper seating in the frame.

AS3 glass characteristics and color

Glass marked as AS3 belongs to a group of windows with enhanced performance properties, often used in body areas where comfort and protection against excessive sunlight are important. The black edge finish and the tinted nature of the glass help reduce interior heating, improve the aesthetics of the car's side profile, and help maintain the privacy of rear-seat passengers.

The black quarter glass blends well with both light and dark body paints, while masking mounting elements and seals, which translates into a more orderly, factory-like appearance of the vehicle after repair.

Benefits of using an original quarter glass

Using an original quarter glass in a Mercedes translates into a number of practical benefits:

• maintaining the factory body geometry in the rear left zone,
• proper cooperation with seals and trim strips,
• visually consistent appearance of the side of the vehicle,
• maintaining appropriate light transmission and radiation protection parameters.

For users concerned about the residual value of the car, it is important that original Mercedes Car Windows make it easier to keep the vehicle in a configuration close to the factory one, which is significant for future resale or professional restoration.

Use in restorations and youngtimer projects

Side windows in good condition are crucial when refreshing vehicles from model years that are beginning to be treated as youngtimers. Replacing a damaged or non-original window with the correct Mercedes component allows for restoring stylistic consistency and improving driving comfort.
