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.

We conduct basic visual inspections and freezing point tests. If the antifreeze's freezing point is insufficient or the engine oil is severely degraded, we will document it. However, considering the shipping duration, we strongly recommend a comprehensive "Full Fluid Service" upon arrival.

The platform has strict internal outbound inspections. If buyers need, we can assist you in commissioning an independent third-party evaluation agency (such as Cha Doctor, Dongche Di official testing, etc.) for re-inspection, with costs borne by the buyer. An independent report can provide more credibility for your local resale.
