GarageVehicleSave 1.0.0
This plugin saves the vehicle you left in the Mission Row police station.
If you want it can also spawn vehicles there on start. To use that feature enable it in the config and set the vehicle model you want to spawn.
You can decide between three different spawning locations. The left, right garage or the parking lot in front.
Also if you leave the garage and you come back later a mechanic fixed your cars.
Installation:
Just place the .dll and the .ini file in the plugins folder and make sure to load it via RagePluginHook.
