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.

If your market is in extremely cold regions (like Russia or Northern Europe), we strongly recommend purchasing ternary lithium (NMC) models equipped with heat pump air conditioning. The range achievement rate of used LFP batteries typically plummets at minus 15 degrees, and we will alert you accordingly.

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.
