The specific process for purchasing a car with a credit card loan from China Merchants Bank is as follows:

1. Call the bank’s customer service number to ensure that you can participate in the credit card loan car purchase business and obtain the approval limit for car purchase;

2. You are required to apply for installment purchase of a car at the dealership with a valid ID card;

3. Fill in the order form for the vehicle you purchased and submit it to the bank for review;

4. After passing the review, you need to pay the down payment, and also need to apply for license plate, insurance, and mortgage (whether mortgage is exempt will be subject to the review standards);

5. Loan the loan and pick up the car.
