Garages
There are several types of vehicle garages in GTA games.
Vehicle Storage
The first is a place for storing vehicles, almost exclusively attached to a Safehouse. A variation on this is the large hangar at the Verdant Meadows airstrip, in which larger vehicles including planes can be stored. The hangar at Las Venturas Airport is only used for spawning the AT 400 passenger plane. In GTA IV, personal parking spaces are provided in front of your safehouse; only 2 vehicles can be stored there at a time.
Vehicle Repair
The second type is a public vehicle repair business. Pay 'n' Spray garages exist in all GTA III Era cities and in GTA IV, and will repair any non-public vehicle, as well as repainting it and replacing the engine to put the Police off its trail, and remove a Wanted Level.
Vehicle Customization
The third type is a customization shop. Transfender, Loco Low Co., and Wheel Arch Angels are public garages in GTA San Andreas from which Car Modifications can be purchased, such as new wheels, spoilers, nitrous, or hydraulics. 8-Ball also operates a bomb shop in which a remote-detonated bomb can be affixed to any vehicle.
Others
Dummy garage are also occasionally available; they are only active for specific missions, in which the player is instructed to deliver a vehicle or some cargo.
