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.

Absolutely. The extreme temperature fluctuations will significantly accelerate the aging of chassis rubber parts, oil seals, and interior plastics. For vehicles frequently dispatched across such latitudes, we will conduct fatigue resistance checks on chassis rubber parts that are twice as stringent as those for vehicles in temperate regions.

100% guaranteed. This is the legal prerequisite for the export of used cars allowed by Chinese customs and the Ministry of Commerce. Any vehicle with unresolved traffic violations (fines/demerits) cannot complete the deregistration process at the traffic management bureau, and therefore cannot obtain a legal export license.
