What does grinding off the serial number mean for a vehicle?
2 Answers
Grinding off the serial number refers to vehicles sold through unofficial channels or cross-regional sales, where the VIN (Vehicle Identification Number) is intentionally erased to avoid accountability for parallel imports by the manufacturer. Additional details are as follows: 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 substandard 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 possess basic maintenance skills, a vehicle with a ground-off serial number can still be an option. If consumers purchase a 'ground-off serial number' product, they can request the manufacturer to issue a certificate proving the product's quality as unqualified, and the manufacturer should provide the corresponding documentation.
I've been repairing cars for over 20 years. The break-in period refers to when a new car is first purchased - the engine, pistons, and other internal components need time to gradually wear in and form properly. Never be impatient by driving too fast or stomping on the accelerator during this time. Aggressive driving increases wear and can lead to issues like oil burning or leaks, and repairs costing thousands aren't worth it. Remember to keep speeds below 100km/h for the first 500 to 1000 kilometers, avoid heavy loads or extremely long trips, and regularly check the engine oil color. Proper break-in not only extends the vehicle's lifespan by several years but also makes starting and acceleration smoother. I've seen too many owners regret not following this advice when their unbroken-in cars ended up scrapped prematurely.
