Is it normal for a new car invoice to have only three copies?

[LeJohn]

It is normal for a new car invoice to have only three copies. Here is the relevant introduction about new cars: 1. Precautions: Avoid emergency braking. Emergency braking not only impacts the braking system during the break-in period but also increases the impact load on the chassis and engine. Mainly check the paint and sheet metal parts. Carefully inspect under direct or backlight—the new car's paint should have no color difference, appearing uniformly full, smooth, and flat; the body sheet metal should be flat without dents, with smooth transitions between parts and consistent gaps at the joints. 2. Maintenance methods: Mainly combined with the first-level maintenance of the car, drain accumulated water and sediment from the fuel tank, and check for oil leaks at pipe joints and switches.
