This is not a normal Insert game, this game uses GUI's that are draggable. To add something to the game go to the GUI that has the 'Add' button on it and click on the grey box beside it and ad a model ID for example: http://www.roblox.com/Working-CFrame-Car-FREE-item?id=80921538 For this one you would use '80921538' as the ID without the quotes and copy and paste that into the grey box using 'ctrl + v' to put it in the box and then click add. Now to delete go to the GUI with the 'Delete' button on it and type in the ID you used to add it Example:(80921538) and click delete the model will now explode and wait 2 seconds then remove itself from the game. Have Fun!
