Who knows the annual maintenance fee of Mercedes-Benz Smart?

The routine minor maintenance cost of Mercedes-Benz smart is 1, 2 1.7 yuan/time, and the major maintenance cost of replacing the oil filter and air filter is 1.975 yuan. When the vehicle travels to 40,000 kilometers, three spark plugs need to be replaced on the basis of routine maintenance, and the maintenance cost when the vehicle travels to 40,000 kilometers is 2,684 yuan.

The specific maintenance fee for one year needs to be calculated by considering the mileage of one year.

The steering oil of Mercedes-Benz smart does not need to be replaced, that is, it is maintenance-free for life.

When the vehicle travels 80,000 kilometers, it is necessary to change the transmission oil in the 4S shop. The price of transmission oil is 288 yuan (excluding working hours), which requires 0.4 working hours of service time.

The replacement cycle of some parts is long, so the cost of parts is not very low. For example, the gasoline filter is 3722 yuan, and the working hours are in 240 yuan. It will cost nearly 4,000 yuan to replace this item when driving to 40,000 kilometers. Considering the replacement every 40 thousand kilometers, this price is acceptable.

However, for smart car owners, the dealer suggested that a bottle of gasoline additive should be added every time the car is filled with oil (about 40L), and the price is 140 yuan, which is unacceptable. According to the calculation of smart car owners' 7L oil per 100 kilometers in the forum, they will spend this 140 yuan almost every six days.
