Are there any tips for insurance companies and four S shops to maintain cars?

Yes Some unscrupulous insurance companies and 4S stores will falsely report the maintenance costs in order to obtain higher profits. It will exaggerate the damage degree of the vehicle and increase unnecessary maintenance items, thus increasing the maintenance cost. In order to reduce costs, some insurance companies and 4S stores will use inferior parts for maintenance. Such parts do not meet the quality standards, have short service life, and even pose a threat to vehicle safety.
