4S dealership records are directly connected to the manufacturer's database, making the data hard to tamper with and the most reliable, with original parts guaranteed; third-party repair shops usually are not connected, making their data unverifiable. Therefore, we only consider the connected records from 4S dealerships as valid historical documentation.

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.

To prevent intermittent failures due to aging of the resistance wire, we will start the engine and set the seat heating/ventilation to maximum for at least 5 minutes, confirming significant temperature changes or airflow output in the cushion and backrest using an infrared thermometer or body sensor.
