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).

We use quantitative standards. Minor scratches less than 3 cm that do not reach the base coat (which can be polished) are considered normal wear; scratches over 3 cm deep to the base coat or dents larger than 2 cm in diameter will be highlighted in the inspection report's "Appearance Defect Distribution Map" with close-up photos.

Under CIF (Cost, Insurance, and Freight) terms, we will insure your vehicle with a reputable international insurance company for "All Risks" before shipment. If total loss or partial damage occurs during sea transport, the risk transfers to you once the goods cross the ship's rail. However, sellwellauto will not stand by; we will assist you in preparing complete claims documentation (such as the bill of lading, invoice, and damage photos) to initiate a cross-border claim process with the insurance company, minimizing your financial loss.
