Is 11 kilometers normal for a new car?

11 kilometers is normal for a new car. Below are the aspects to check for a new car: 1. Manufacturing date: Open the front passenger door to check the vehicle's manufacturing date. For domestic cars, it should not exceed six months; for imported cars, it should not exceed 10 months. If the date exceeds these limits, it indicates a stock car. Then, check the number in the lower left corner of the windshield. The first digit 'L' indicates a domestic car, while other digits indicate an imported car. The 10th digit represents the model year. 2. Tire and glass production dates: Check the production dates of the tires and glass. For tires, locate these four digits on the tire—the first two digits represent the week, and the last two represent the year. For the glass production date, look at the bottom digit. For example, if it's '9,' it represents 2019. If the dot is after the digit, subtract the number of dots from 13; if the dot is before the digit, subtract the number of dots from 7. This represents the month of glass production. The production dates of the glass and tires should be before the vehicle's manufacturing date. 3. Interior condition: Check the engine oil and exhaust pipe. The engine oil of a new car should be light in color. Then, touch the inside of the exhaust pipe. If the engine oil is black and there is black carbon buildup inside the exhaust pipe, it indicates the car has significant mileage and might be a test-drive car. Check if all electronic and audio systems in the car are functioning properly. The odometer reading of a new car should not exceed 50 kilometers. Check if there are plastic protective films on the seats, door panels, etc., and if all the included tools are complete.
