When buying a car, you need to provide relevant documents and information, such as ID card and driver's license, so that the dealer can handle the relevant formalities for you. If you buy a car with your legitimate income and meet the relevant regulations, then you are completely free to buy a car.

However, it should be noted that if you choose to buy a car by loan, you need to submit assets certificates, personal credit reports and other related materials to the bank so that the bank can review the loan qualification. In the process of buying a car, whether it is a full payment or a loan, you must abide by the relevant regulations and do not engage in any illegal acts. If illegal acts are involved, they may be investigated and dealt with by relevant departments and bear corresponding legal responsibilities.
