If you have available credit, and the 4S store also accepts credit cards, then you can buy a car with a credit card, but there will be problems when applying for installment.

If you want to apply for installment, the installment limit is set at 100% of the permanent limit of your credit card. Suppose your permanent limit is 40,000, and now you apply for an adjustment to 60,000 yuan, then you can spend 50,000 to buy a car, but the maximum installment amount you can apply for is 40,000, and after you make the installment, this part of the amount will occupy your credit card in full As for the quota, the quota will be gradually released only after you deposit and repay each installment.

You now have two options. First, you can go to the 4S store and ask if they have cooperation with China Construction Bank. If they have cooperation, you can apply for car purchase installment. The amount of this installment is relatively large, and after the application is successful, it will be separate from your card limit. It is a special limit, so it will not affect your usual use of the card. Second, you use the temporary quota to buy a car, and then apply for bill installments according to the maximum installment amount you can apply for. Apply for more than 12 installments before the end of March and there will be a handling fee discount. You can go to their credit card website to check it out.
