I can tell you something about my classmates' previous methods, and you can refer to them.
I rented six cars directly from the car rental company. The stolen car is BMW, with more than 600 cars a day, followed by five ordinary cars, with an average of 150/ day. Of course, I paid for the trip myself, but it's only the fuel cost, which is definitely much cheaper than 3 yuan/km.
Of course, the premise is to find six friends with driver's licenses to help you drive.
