Foreign students can't apply for installment payment when buying duty-free cars, because the manufacturer of duty-free cars requires customers to pay a specified amount of car money at one time, which is different from buying a car in an ordinary bridge car 4S shop. Of course, this does not mean that you can't pay by installment if you buy a duty-free car. Only in this way, customers who need to buy duty-free cars can negotiate with local commercial banks and get the loan results of installment payment, so they can pay loans to the competent commercial banks regularly in the original way, without contacting the duty-free car manufacturers, let alone the agency.
