Five points for attention when buying a car with a loan: 1. Watch out for two mortgage. Although this problem rarely occurs, car owners should be wary of their cars being mortgaged by dealers for the second time, leading to loan fraud. 2. Don't be fooled by low monthly payment. When auto financing institutions publicize, they often don't directly state the interest rate, but say monthly and daily repayment, such as "only one day to repay the loan 18 yuan".
