What does grinding off the serial number on a vehicle mean?

[Chris]

Grinding off the serial number on a vehicle refers to the practice of selling cars through unofficial channels or across regions, where the vehicle identification number (VIN) is intentionally removed to avoid accountability for cross-regional sales by the manufacturer. Additional information: Generally, purchasing from reputable stores ensures genuine products with qualified quality and craftsmanship, and the store will provide its own warranty. However, there is still a possibility of encountering defective or counterfeit products. The main difference lies in whether the warranty is honored, as large authorized dealers often only provide warranties for vehicles sold locally. If you have basic knowledge of vehicle maintenance and repair, opting for a car with a ground-off serial number might be a viable choice. If consumers purchase a product with a ground-off serial number, they can request the manufacturer to provide a quality certification for the product, and the manufacturer should issue the corresponding certification.
