If a car of more than 400,000 runs 365 days a year, it will take more than two years to earn so much back, but it is actually just the money at the front. Now, the fuel cost is rising year by year. After deducting the high-speed fee, maintenance fee and labor fee, it is only enough to maintain the car loan, but after two years, the car is worthless. The more you run, the faster the car will be scrapped. Now, the emission standards will be upgraded rapidly, and maybe you don't have to wait.
