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).

The nameplate date is the absolute time when the vehicle leaves the factory; the registration date is when the vehicle is registered with the traffic management department after sale. The difference represents the time the vehicle spent in the dealer's warehouse or logistics. If the time difference exceeds 6-8 months, the vehicle is considered a "stock vehicle," and we pay special attention to the natural aging of its rubber components.

The storage area at the roll-on/roll-off terminal is entirely outdoors, which is standard practice at ports worldwide. During the few days vehicles wait to be loaded, they will inevitably be exposed to sun and rain and accumulate dust. We will not provide custom car covers as this would significantly hinder the efficiency of dock workers moving vehicles.
