Odors are difficult to convey through images, so our quality inspectors conduct subjective smell assessments and record them. For vehicles with severe smoke or mold odors, if deep ozone sterilization is ineffective, we will downgrade the vehicle and mark the report with a red "Odor Warning" at the top.

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.

China has centralized vehicle records you can check remotely before paying anything. Ask the exporter for the 17-digit VIN, then request two reports. First, the maintenance history: third-party platforms pull 4S dealership records showing service dates, mileage and repair items. A mileage line that goes down over time is a red flag for odometer tampering. Second, the insurance claim history: it lists accident dates, claim amounts and repaired parts. Heavy claims involving frame rails or airbags should end the deal. Practical tips: run the reports yourself instead of accepting screenshots from the seller, make sure the report date is close to the delivery date, and cross-check with physical wear such as the steering wheel, pedals and seat bolsters, which cannot lie about high mileage. Keep in mind that small private repairs never enter these databases, so combine history checks with a physical inspection before shipping.
