This situation is quite dangerous. If CCB knew that the car was transferred and lost in two months. The installment payment may be terminated early, and the entire amount will be credited to the account at once and the cardholder will be required to repay it. Your friend is engaged in credit card car purchase installment business, not vehicle mortgage loan business. The credit card car purchase installment is a kind of credit consumption. It depends on the person's income, personal credit, asset status, etc. to determine how much credit he can give. If it is not enough, you can use your personal credit to guarantee him, and the guarantor is also Be jointly and severally liable for repayment. So there is no need for vehicle mortgage. Now the only thing I can do is to ask your friend to quickly take the money from selling the car and pay off all the installments, so as to avoid financial disputes in the future when the money is spent.
