Once the car system (especially in a closed ecosystem) undergoes a major version upgrade, its bootloader is usually locked, preventing downgrades. If this happens, there is basically no solution in an overseas environment. Therefore, we strongly warn: do not blindly insert a USB drive to upgrade while offline.

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.

A professional pre-shipment inspection typically costs a small fraction of the vehicle price and routinely pays for itself. A thorough inspection covers: paint thickness measurement across 30+ points to map body repairs; structural assessment of pillars, rails and crossmembers for accident damage; engine and transmission operation; a full electronic scan for fault codes; suspension and underbody checks for leaks and rust; and, for EVs, battery SOH and thermal management performance. You receive a written report with photos before the car is loaded — if the car fails, you can stop the shipment or renegotiate. Skipping the inspection to save a small fee is the classic false economy in used car importing: discovering a problem after arrival is far more expensive than preventing it at origin.
