1, vehicle loan processing channel. There are three channels to handle automobile mortgage: banks, car dealers or car companies, and 4S shops cooperating with banks. 2. Down payment, interest, repayment method and time limit. The down payment of bank car mortgage loans is generally 20%, and some are 30%. In the 4S shop that cooperates with the bank, the down payment will be implemented according to the regulations of the bank, but some designated models will engage in some promotional activities of 0 down payment. Many auto financing companies or auto companies' own auto loan products do not require down payment, even if there is, it is generally 20%. In terms of interest, the annual interest rate of banks is generally between 2.4% and 4%, and there are no other charges (some of them used to need guarantee fees, but now they are rare, especially credit card car installment), and the interest rates of the four major banks will be lower than those of other commercial banks. Auto financing companies or dealers don't charge interest, but only charge a handling fee (so don't be fooled when you see an advertisement with 0 interest). The annual interest rate is similar to that of banks, and some will be higher. In addition to the handling fee, many people will charge other fees, such as mortgage fee, mortgage fee, GPS installation fee or mortgage insurance fee. All car loan repayment methods are equal principal and interest or equal cost, that is, the repayment amount is the same in each installment, with fixed interest and principal. In terms of time limit, bank car loans can generally be processed for 1-3 years, some banks can handle qualified customers for up to 5 years, auto financing companies or dealers can generally handle it for 5 years, and some models can only handle it for up to 3 years.
