All our measuring instruments (especially calipers, paint thickness gauges, and refrigerant pressure gauges) are calibrated quarterly according to ISO quality management system requirements to ensure the data we provide you is objective, accurate, and reliable.

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.

We can purchase the hardware (diagnostic device) on your behalf. However, the original online diagnostic accounts (especially those involving anti-theft programming and module matching) have strict domestic IP location and real-name authentication restrictions, making it very difficult to log in stably from overseas for a long time, and we cannot guarantee technical support for this.
