Vehicle modifications refer to changes made to a vehicle's appearance, performance, or functionality. These alterations can include adding new parts, changing the paint color, or upgrading the engine. Common modifications are custom wheels, suspension upgrades, and aftermarket exhaust systems, which can enhance both aesthetics and performance. Many vehicle owners modify their cars or trucks to express personal style or improve driving experience. Some modifications may also increase safety or fuel efficiency. However, it's important to ensure that any changes comply with local laws and regulations to avoid potential legal issues.
