The amount of customization available varies for each car model.
It offers customization options for about 65 different car types. TransFender is a play on the word 'transgender'.
A Nitrous system is available in 3 different 'strengths', 2×, 5×, and 10× (these options indicate how many times you would be able to use a nitro 'boost'). Most items will vary depending on the vehicle, but wheels cost $620 to $1560, custom paint jobs are $500, stereo upgrade is $100, and a hydraulics system is $1500. Many items can be purchased and/or upgraded at these garages Paint Jobs, Vents, Hood, Exhaust, Spoilers, Lights, Nitrous, Roof, Wheels, Stereo, and Hydraulics. In GTA San Andreas, each garage opens at certain times in the storyline, due to the islands being locked, or, in Los Santos' case, the mission has not been reached.
