If car companies, four S stores and banks cooperate in marketing and provide two-year interest-free and fee-free car purchase activities, you don't need to pay extra, just provide your personal credit information and personal data. It should be noted that car buyers' banks with poor personal credit information may refuse to provide loans.
If you apply for a loan to buy a car with a car credit card issued by the bank, the fourth S shop does not provide corresponding services, and the bank will charge a little handling fee when there is no interest.
