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.

Most leading Chinese brands' car systems support "offline voice commands" (like adjusting temperature and opening windows). However, if recognition fails due to accent or language limitations (only standard Chinese is supported), you can always control it via the physical screen.

Two separate protections matter: cargo insurance and contractual risk transfer. Cargo insurance: for container or RoRo shipments, buy marine cargo insurance covering total loss and damage, typically 110% of the CIF value (average cost 0.3%–0.8%). Check exclusions — many policies exclude pre-existing damage, so a pre-shipment inspection report is essential to prove the car's condition at loading. Incoterms define who bears risk and cost at each stage: 1. FOB (Free On Board): exporter pays until the car is loaded on the vessel; risk passes to you at that point. You pay ocean freight and insurance. Common and usually cheapest if you have your own freight forwarder. 2. CIF (Cost, Insurance and Freight): exporter pays freight and minimum insurance to your port. Convenient but the insurance coverage is basic — consider topping it up. 3. EXW (Ex Works): you handle everything from the exporter's yard; only choose this if you have a trusted agent in China. Put the agreed Incoterm and port clearly in the contract, and never release final payment before the Bill of Lading is issued.
