Question: The Springfield Police Department in Illinois used to use what rear-wheel drive full-sized car for their patrol vehicles?
Context: Police emergency wagon is a North American term for a station wagon put into police use with police car variants.  They are usually used as K-9 units, Bomb Squad units, patrol units, emergency units, or assistance units.  By the 1980s, Police emergency wagons had begun to be phased out by most police forces by the arrival of the Police SUV and special service packages.  Some police forces, such as the New York City Police Department and the Chicago Police Department, still use Police emergency wagons.  With the arrival of the Dodge Magnum Police Package in 2006, Police emergency wagons may be put back into standard use into the future.
