2. When to pick up the car. This is also very important and often overlooked. Sometimes, you pay a long deposit, but you just can't get the car. 4S promised to let him write a note after the time to pick up the car, not to let him pick up the car for a long time and ask him to return the advance payment (deposit).
3. After-sales service and maintenance. In this era, buying a car is easier than maintaining it. As soon as the car drives home, endless things always need to be done by yourself.

2 Fuel economy
The fuel economy of a car is often measured by the fuel consumption of the car 100 km under certain working conditions or the mileage that a certain amount of fuel can make the car run. In China and Europe, the unit of automobile fuel economy index is L/ 100km, that is, the number of litres of fuel consumed when the automobile travels 100km. The smaller the value, the better the fuel economy of the car, and the more fuel-efficient the car will be. In the United States, it is expressed by MPG or mi/gall, that is, kilometers per gallon of fuel, which means miles per gallon of fuel. The larger the value, the better the economy of the car and the more fuel-efficient. Fuel economy is related to many factors, such as driving speed. The fuel consumption of a car is the lowest when driving at a medium speed close to low speed, and it increases rapidly with the increase of vehicle speed at high speed. In addition, the maintenance and adjustment of the car will also affect the fuel consumption of the car.
