2021 Geely Yuanjing X6, 1.4 automatic luxury version, one owner, no accidents, has driven 44,000 kilometers safely.
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).
Use credit check apps (like Check Doctor or Ant Queen) to pull the complete accident record.
Most basic maintenance reminder lights (like for changing the air conditioning filter) can be manually cleared using a combination of steering wheel buttons or through the engineering mode on the central control screen. We will provide internal guidance manuals for these hidden operations to our B2B clients.
