Mileage Verification

• Confirmed odometer readings
• Vehicle history reports
• Documentation from previous owners

Quality Testing Procedures

• Compression testing to check internal engine health
• Leak inspection for oil and coolant
• Visual inspection for wear and damage
• Performance testing where applicable

These tests ensure that the engine meets acceptable performance standards before being sold.
