I'm trying to make a command that spawns a car, When i want it to spawn, i would like it to spawn via command and at a position. Is there any way after i'm done with that car, or any cars i go to the position and just despawn it from the server?
e.g. Like i go to a spot and type /car 1 and that spawns me a sultan for example, And then when i'm done with that car to prevent other people from getting it when i'm offline to despawn it?
