A century-old heavy rainstorm caused heavy losses to many people, and many cars parked on the streets in the hardest-hit areas are believed to have died heroically. However, it is time to start again after the wind and rain. In case my car unfortunately becomes flooded in this black rain, should I go for maintenance? In theory, a flooded car can be repaired, but it may take a lot of manpower and material resources and a large number of replacement parts. In the end, the cost may be similar to buying a new car.
