Does the subject want to ask "where is the pain point of second-hand car tax?" The pain point of second-hand car tax lies in opaque taxation, complicated and changeable taxation standards and difficult taxation.

1. The calculation of taxes and fees is opaque. Taxes on used cars include vehicle purchase tax, vehicle and vessel tax, transfer fees, etc. However, there are differences in tax standards for vehicles in different regions, different models and different car ages, which leads to opaque calculation and difficult to determine the cost of car purchase.

2. The tax standard is complex and changeable. Different provinces and cities have different tax standards for used cars, and the tax standards are often adjusted, which makes it difficult for car buyers to understand and master the latest standards in time.

It is difficult to pay taxes and fees. Car buyers need to go through the relevant formalities at the vehicle management office or the tax bureau and pay certain taxes. However, in this process, they may encounter problems such as long waiting time and cumbersome procedures, which increase the time and energy costs of car buyers.
