The correct answer by me is: As mentioned, it's typically impossible to insure a car that you don't own because insurance companies want you to prove you have insurable interest in the car. If you can't prove you have a financial stake in the vehicle, it's unlikely that you will be able to find an auto insurance company willing to cover you.
