Will 4S stores replace parts inside new cars?

[MacDylan]

Generally, 4S stores will not replace parts inside new cars for the following reasons: It is not cost-effective in terms of time and money: Removing a part from an entire car, such as replacing an air conditioning component with an aftermarket part, may yield some profit, but this profit is not worth the labor cost. After all, removing a part is a very labor-intensive task, so it would be more practical to source aftermarket parts from the second-hand market directly. Under normal circumstances, no one would be willing to do such thankless work, as the effort simply doesn't justify the labor cost. Strict management: The automotive industry is currently very challenging, leading to increasingly strict management.
