GGMM, or GTA Garage Mod Manager, is a tool for installing and managing modifications to GTA III Era games, created by Jernej L, also known as "Delfi". It allows the user to install, uninstall and view modifications. These include car and weapon modifications. The user can look at the model of a vehicle without actually entering the game, and there are controls such as "Damaged" - this puts the vehicle model into its most damaged form. "Wireframe" - this hides the polys of the mesh, showing only the outlines of them. "Low Quality" - this puts the vehicle into its "distance model" - the model a vehicle becomes when it moves beyond a certain distance away from the player, for performance reasons. You can put modifications on the vehicle (e.g. Body parts).
