Buy an elegy. The car does not need to be delivered for it to work. Have both players enter the most expensive car. Have the passenger hold down on the d-pad and pick a character. When asked "are you sure" do not press anything. Have the driver drive out for a few seconds and then back in. Have the driver move the most expensive car to the elegy. Then get into the most expensive car. The car you HAVE TO sell is the one in the original spot, not where the elegy is. Go to LSC and sell it. Have the passenger exit the "are you sure" screen. The player should be glitched in an animation. Go to the Playstation Store through the pause menu and then exit the store. You may be in Passive Mode after exiting the store. Rinse and repeat.
