The car loan was not paid back on time for two months. After the car is impounded by the guarantee company, you need to pay 15000 yuan to get the fare back. Do I refuse to pay?

Failure to repay on time is essentially a breach of contract, and you should have paid the responsibility.

As for how to be responsible, it depends on how long you have been in breach of contract. General guarantee companies have the latest repayment time. If you don't return the car after February, it may really be disposed of. If you want your car back, it is normal for them to ask you for the fare.

However, you can ask them about the details and basis of the fare, and then hire a lawyer to see if you can save some money. If not, you can only pay.
