The index of special operation vehicles is different from that of passenger cars. The state stipulates that only passenger cars can update vehicles, and there is no other special way.
If special operation vehicles can be replaced after five years, wouldn't it be an indicator of passenger cars? Then the lottery is equivalent to nothing.
It is impossible for two different indicators to be converted to each other. I wanted to buy this kind of car. Later, I checked the information online and went to several places where cars were sold to learn more about it. It's silly to say that I can change trains.
