Sorry for my bad english.
You will need SparkIV or OpenIV to install this.

With OpenIV you will need to Select Edit mode before you start modding
OpenIV - http://openiv.com/
SparkIV - http://www.gtainside.com/en/gta4/tools/28310-sparkiv-0-6-6-iv-eflc/

Open SparkIV or OpenIV and search for pc/models/cdimages.
Then open vehicles.

Import the Faggio file into there (With SpartIV you will need to click Save)
Start GTA IV and you are done!

Have fun!
