Vehicle performance is good. Structural, reinforced, and cover panels have no accident-related damage or repairs. The three-electric system (battery, motor, electronic control) has no damage.
Accident inspection: main structure, reinforced parts, cover panels, and hinges have no damage or abnormalities. Engine bay: key mechanical components are normal. Exterior: no issues. Interior: most features are normal; airbags, seatbelts, dashboard, and instrument cluster are normal; lighting system is normal. Startup test: OBD shows other fault codes. Onboard tools: none.
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).
This involves personal privacy, and we have no right or ability to retrieve personal driving violation records from the traffic police system. We can only infer if there was aggressive driving by checking if the engine has been reprogrammed with a higher-level ECU (stage 1/2) or if the transmission has a history of severe overheating.
As rubber seals age, "slight oil seepage (oil stains but no dripping)" is very common in used cars and is not considered a major fault. Our recommendation is: as long as the oil level does not drop abnormally, just clean and monitor it regularly after arrival, without the need to immediately incur high costs to disassemble and replace the seals.
