All features/activities available to the player in the Have A Heart mission.
To complete this mission, it is not at all necessary to take the car to the doctor. She (the car) can simply be blown up or drowned and the mission will be completed, the main thing is to drive a decent distance from Elizabeth's house. The disadvantage of this method is that Niko will not receive money (reward). Also after that you can hear a unique dialogue with Elisabeth. If you need money, then the car must be taken to the doctor.
