New car deliveries typically show a mileage between 15 to 38 kilometers, which mainly consists of the sum of factory testing mileage and transportation mileage. 1. Generally, the total mileage of domestic new cars does not exceed 50 kilometers. This is because more practical influencing factors may exist and need to be taken into account. 2. For imported vehicles, considering factors such as overseas transportation, port loading, and customs clearance, a mileage within 100 kilometers is considered normal. A new car showing 0 kilometers is not credible. Since manufacturers conduct mandatory tests before delivery, even brand-new cars will have some mileage. Buyers should be cautious about this situation when purchasing a new car.

I've bought three brand-new cars, and based on my experience, typically under 30 kilometers is ideal. My Japanese car had only 8 kilometers on delivery. New cars need road testing after production, then transportation and loading/unloading, and dealerships perform PDI inspections—all of which add mileage. The most extreme case I've seen was when a transporter drove to the wrong warehouse, resulting in a new car with 90 kilometers—such cases warrant demanding a replacement. Additionally, stock cars might be moved frequently, easily pushing mileage over 50 kilometers. When picking up the car, focus on tire hairs and chassis dust; high mileage with a fresh condition is fine, but beware of odometer tampering.

Last time when I accompanied my friend to pick up the car, I chatted with the manager about this. He said the industry default is that anything within 50 kilometers is considered normal. The transport vehicle drives about 5 kilometers from the factory to the parking lot, moves 2-3 times during loading and unloading, plus the dealership conducts over a dozen dynamic tests, so 20-30 kilometers is very common. But he quietly mentioned that if it exceeds 100 kilometers, you should be cautious, as it might be a display car or a returned/exchanged vehicle. He especially reminded to pay attention to the manufacturing date—if the car is over 3 months old and has high mileage, it might have been relocated multiple times between warehouses.

During a visit to an automobile manufacturing plant, I learned that every vehicle must undergo a 3-5 kilometer road test before leaving the factory. During transportation, the distance from the plant to the transfer station typically ranges from 5 to 15 kilometers. After being received by the 4S dealership, an additional dynamic inspection of approximately 10 kilometers is conducted. Therefore, I believe that up to 30 kilometers is completely normal, and even 50 kilometers falls within a reasonable range. If the mileage exceeds this, it's necessary to check the records to see if the car has been used as a display vehicle. When picking up the car, remember to check the inside of the exhaust pipe—it should be clean for a brand-new car, while one that has been driven for several dozen kilometers will show noticeable carbon deposits.

With 10 years of auto repair experience, I've handled dozens of new car disputes. According to national standard GB7258, a new vehicle's delivery mileage is compliant if it doesn't exceed 0.8% of total range. For example, a 400km-range EV under 3km is reasonable. Gas-powered cars are typically acceptable within 30km. The most common dispute I've encountered involved a customer finding 60km mileage - investigation revealed it was used as a wedding lead car, which qualifies for compensation. The key is checking chassis bolts for tightening marks to avoid purchasing refurbished vehicles.

Last week, I helped my cousin inspect his new car and felt relieved when the odometer showed 17 kilometers. The salesperson mentioned that new car transportation is now fully monitored, with every kilometer recorded for its purpose. Normal transportation shouldn't exceed 20 kilometers, and PDI inspections typically add no more than 5 kilometers. However, a reminder for everyone: in winter, pay attention to the tire pressure monitoring system. Some cars might have their sensors disconnected to save power while charging, which increases mileage without recording data. It's best to request the dealership to provide a transportation route map, which is more reliable than just checking the odometer.
