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.

We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).

It usually refers to very small stone chips on the hood from high-speed driving, nail scratches on the inside of door handles, slight curb scratches on the edges of wheels, and minor wear on interior plastic parts. These do not affect the vehicle's functionality or corrosion resistance.
