The company used your ID card to borrow money to buy a car. You signed a loan-free agreement with the company, which is valid between you and the company, but not for the bank. The bank will ask you to repay the principal and interest on a monthly basis according to the car loan contract. If you don't repay on time, you will be sued and even affect your personal credit. So it is risky and prudent for you to allow the company to buy a car with your ID card.
