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.

Our system provides basic risk alerts based on the general regulations of the main exporting countries, but the final responsibility for confirming whether the vehicle meets the import country's regulations lies with the buyer. We will rigorously indicate the vehicle's production year, first registration date, and Chinese emission standards (such as National V, National VI) on the details page. We recommend that you submit this accurate data to the local vehicle management department or customs agent for verification before placing an order.

We will never perform blind deep disassembly unless there are clear severe fault codes or extreme noises. The sealing of the engine and transmission is crucial, and compromising the factory seals to investigate non-existent issues is unprofessional. We rely on data flow and external acoustic and fluid analysis to make judgments.
