You may think they carry around members of the world-famous rock bad, but police cars serve practical purposes of carrying around law enforcement officers. These cars come in standard makes and models of law enforcement vehicles, including Dodge and Ford sedans. Police cars see frequent use among members of police teams, helping officers of different units perform patrols and respond to various incidents. These cars provide transportation, help move suspects, and help officers patrol large areas. Some cars feature a low profile with minimal exterior designs and equipment, like flashing lights. Others, however, come with special trim painting, bearing logos of local police forces and featuring words like "police" and "911." Cars bearing external features, such as megaphones, sirens, and roof lights, classify as marked cars. Those without light configurations count as unmarked. Among the types of active cars on duty, Dodge Charger police cars are among the most popular. These cars come in sedan styles. They feature fast acceleration, quick braking, and provide plenty of interior room for storing equipment, like radios and gear. On eBay, you can search a large inventory of these vehicles, along with accessories, like police car lights. You can look for active models as well as older cars, like vintage police cars.
