What are the reasons for a 4S shop to recommend replacing a car door?

[McIan]

4S shop recommends replacing car doors for the following reasons: Dented car door: If the car door has minor scratches or dents, it can be repaired and there is no need to replace the door. However, if the damage to the door is severe, deformed, or covers a large area, replacement is necessary. Installing a new car door would be more reassuring. Safety aspects: The car door provides access for drivers and passengers to enter and exit the vehicle, isolates external interference, and to some extent mitigates side impacts to protect the occupants. The aesthetics of the car are also related to the design of the door. The quality of a car door is mainly reflected in its anti-collision performance, sealing performance, and ease of opening and closing, among other functional indicators. Anti-collision performance is particularly important because during a side collision, the buffer distance is very short, making it easy for the occupants inside the vehicle to be injured.
