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).

Our responsibility ends with delivering the vehicle to the Russian border or Far East port and providing the legal Chinese export documents. The payment of Scrap Tax, application for SBKTS (Vehicle Structure Safety Certificate), and activation of the final e-PTS electronic passport must be fully handled by the Russian buyer and their local customs broker.

4S dealership records are directly connected to the manufacturer's database, making the data hard to tamper with and the most reliable, with original parts guaranteed; third-party repair shops usually are not connected, making their data unverifiable. Therefore, we only consider the connected records from 4S dealerships as valid historical documentation.
