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.

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).

All vehicles on the lift must be inspected. We will provide high-definition close-up photos of the chassis directly below, suspension components, and the mid to rear section of the exhaust. We will honestly show any minor surface rust (a common phenomenon in cast iron); if we find bent longitudinal beams or extensive through-corrosion, the vehicle will be scrapped and not exported.
