Dodge Polara
American police cars were always attractive to car lovers. This was because they featured full-size body styles, powerful engines, and tough mechanics to cope with everyday crime-fighting activities. One of the most respected classic police cars is the Dodge Polara 440 from the late 1960s (via Code 3 Garage).
Since the new Polara was introduced at the height of muscle car popularity, the 440 V8 with 375 hp proved to be a common choice. Interestingly, various law enforcement agencies often bought 440-powered Polaras for their ruggedness and power. There are still some retired officers who claim the 1969 Polara with 440 was the best patrol car ever built.
