certified speedo

"The city cars often had a six cylinder, or a low power V8 since they would not be used for high speed pursuit. The New York City police department ordered a lot of cars with a slant 6. Imagine driving a Plymouth Fury police car with a slant 6. But then again, how much high speed driving would the average police officer be doing in NYC anyway?"
