Hello, my answer is as follows: 1. It is unreasonable for the loan company to take back the car several days overdue, so it can call the police. 2. Article 207 of the Contract Law stipulates: "If the borrower fails to repay the loan within the agreed time limit, it shall pay overdue interest in accordance with the agreement or relevant state regulations". The repealed "Economic Contract Law" and "Regulations on Loan Contracts" have clearly stipulated that overdue loans should be penalized. The Notice of the People's Bank of China on Interest-bearing Measures after Adjustment of Loan Interest Rate (hereinafter referred to as the Notice) and 1999 Regulations on the Administration of RMB Interest Rate (hereinafter referred to as the Regulations) have detailed provisions on the calculation and collection of interest on overdue loans, and the Supreme People's Government also has detailed provisions on such issues.
