In the PC version of GTA 1, the police cars (along with the Ambulance and the Fire Truck) will have their radio tuned to Brooklyn Underground FM, unlike all other renditions throughout the series which only have the standard police dispatch radio. In Liberty City, the Squad Car is rounded vehicle with blue-white livery, appearing similar to a 1990s Chevrolet Caprice, with a 1990s NYPD livery the San Andreas/ Vice City variants are actually adaptations of the Portsmouth, with the San Andreas version bearing a black-and-white body color design (like its real-life San Francisco counterpart) and similar angular body design, and the Vice City rendition being colored blue and white but features a modified body that appears wider and rounded.
Three variants of the car exist, each appearing in one of the game's three cities. In Grand Theft Auto 1, the police car is known as the ' Squad Car'.
