To apply for CCB car installment plan, you must use a CCB credit card! To purchase a car in installments, you need to provide a credit card, ID card, employment certificate or real estate certificate to apply for a special limit to purchase the car, and then pay it back to the credit card in installments. It won't occupy your credit card limit. The CCB credit card website has a detailed introduction. Attached is a flow chart of car purchase installments for your reference. I hope it will be helpful to you.
