The lifespan of rubber sealing strips for frameless doors is usually only 4-5 years. We carefully press the sealing strip at the edge of the roof to check for loss of elasticity and use a high-pressure water gun to wash the seams of the windows to check for direct water leakage due to aging.

We will provide the transfer record from the vehicle registration certificate. A high number of transfers does not necessarily indicate poor condition (for example, internal transfers within a family for quota purposes), but we will consider it a risk factor and conduct a more thorough physical inspection to verify its actual condition.

Do not use a high-pressure water gun directly! The high-pressure water can instantly damage the fragile aluminum fins of the condenser, leading to a permanent decrease in cooling efficiency. We can only use a low-pressure air gun or a soft brush for surface cleaning.
