According to the car price of 600,000 yuan, the down payment is 30%, and the balance is divided into three years plus interest. The average monthly repayment amount is about 1.4 million yuan. Personally, I think other aspects have little influence. According to the fuel consumption of 20L/ 100 km, the normal vehicle does not exceed 1800 km per month, and the fuel consumption is about 2800 yuan. Faced with these two major expenses and other expenses, if the monthly expenses exceed 17000 yuan, then your monthly income is at least 25000 yuan and your annual income is 300,000 yuan. Even so, it will affect your quality of life for three years.
