Buyers must prioritize the engine condition and mileage, as these directly impact the remaining service life. Inspect the chassis for structural integrity, ensuring there are no signs of heavy rust, cracks, or unauthorized welding. Verify the load capacity (GVW) to ensure it meets your specific hauling requirements, and check the deck material (steel vs. wood) for durability based on your typical cargo. Additionally, confirm the emission standard (e.g., Euro 4, 5, or 6) to ensure the vehicle can be legally operated in your target region.
