Car accessories refer to additional items and features that are not part of the standard equipment of a car but can enhance its functionality, appearance, and comfort. They can range from practical items such as floor mats, seat covers, and car chargers, to decorative items like window decals and steering wheel covers. Other popular car accessories include GPS navigation systems, dash cams, and car audio systems. Car accessories can be purchased from auto parts stores, online retailers, and some car dealerships.
