Legal analysis: it is not illegal to help a friend borrow money to buy a car. But it is risky to help others borrow money to buy a car. If the lender can't pay back the money, or maliciously overdue, then the lender has the responsibility to pay off the arrears. If the loan is not repaid, if it is overdue, its credit will also be affected.
