Many Need for Speed games allow players to customize their cars extensively, but one of the most popular games in the series for customization is Need for Speed: Underground 2, released in 2004. In this game, players can modify almost every aspect of their car's appearance and performance, including the body kit, paint, decals, wheels, and suspension. Players can also upgrade their engines, brakes, nitrous, and other performance parts to improve their car's speed and handling. Additionally, players can customize their car's sound system and install neon lights, making it a very comprehensive and immersive customization experience.
