You can register the sports car business on apps such as Didi taxi or Shenzhou bicycle, and you can take passengers to earn some extra money when you are free.
Long-term idle cars can be placed in rental companies to earn rent.
If you have a car that has been idle for a long time, consider calling the car rental company. They will pay the rental fee by the day, so you don't have to worry about the repair fee after the car is scratched. If your car is better, you can also rent it to a wedding company, so the income is still considerable.
