Purpose and body fitment

The presented window is designed for installation in the front – left side zone, which guarantees a proper fit to the door structure of the C140 series coupé. The appropriate edge profile and factory geometry facilitate correct seating in the guides and smooth operation with the window lifting mechanism.

By maintaining the manufacturer's original specifications, the component remains compatible with factory seals, moldings, and fittings, which reduces the risk of leaks and unwanted noise while driving.

Characteristics of AS2 green glass

Glass marked with the AS2 class is a standard used in vehicle side windows, ensuring adequate light transmission while limiting excessive interior heating. The green tint improves the visual comfort of the driver and passenger by reducing glare and increasing visibility in sunny conditions.

Selecting a window with the correct class and color is important not only for aesthetics but also for functionality – it affects driving ergonomics, mirror visibility, and the visual consistency of the entire glazed part of the body.

Condition of the component and benefits of choosing a used part

The offered window comes from the secondary market, which allows for combining a reasonable purchase cost with the original build quality characteristic of the Mercedes brand. A used component from factory production often fits existing bodywork better than replacements with uncertain dimensional tolerances.

Choosing such a window is particularly beneficial when restoring or repairing classic vehicles and youngtimers, where maintaining compliance with the original specification is of both technical and collector significance.

Safety, functionality, and installation

The factory side window for Mercedes is designed as a passive safety element – in the event of damage, the glass breaks in a controlled manner, minimizing the risk of serious injury. A correctly selected and installed component ensures door tightness, stable operation of the lifting mechanism, and appropriate structural rigidity.

During installation, it is recommended to:

• check the condition of the guides and seals before seating the glass,
• precisely adjust the position in the lifting mechanism,
• verify door closing and seal adhesion after installation.
