Vehicle customization refers to the process of modifying a vehicle to reflect the owner's personal style or improve its performance. This can include changes to the exterior, such as paint jobs, decals, and body kits, as well as interior modifications like new upholstery and upgraded sound systems. Additionally, vehicle customization can enhance functionality through performance upgrades, such as improved suspension, exhaust systems, and engine modifications. Enthusiasts often engage in this practice to create a unique driving experience or to participate in communities centered around customized vehicles, such as car shows and auto clubs.
