GTA San Andreas Car Installation Tutorial

There are many ways of uploading a car into GTA San Andreas.
What I am going to do is to explain one of the simpliest ones.
The name of the programme GGMM which means GTA Garage Mod Manager
You can upload the car modes downloaded into the game by pre-viewing it.
To start with,please downloade the programme from the link given below and extract the zipped game on to the file where you have previously set it up.(For Example; C:\Program Files\Rockstar Games\GTA San Andreas)
