Modified cars are vehicles that have been altered from their original factory specifications. These modifications can include changes to the engine, suspension, exhaust system, and bodywork. Enthusiasts often customize their cars to improve performance, enhance aesthetics, or personalize their driving experience. Common modifications include installing a turbocharger for increased power, upgrading brakes for better stopping performance, and adding aftermarket wheels for a unique look. Some modifications are purely cosmetic, such as custom paint jobs or body kits, while others focus on improving functionality and handling.
