Nothing's as bone chilling as a cop car coming up on you in the rearview. A harsh grille, spotlights and flashers hanging off of it like a cowboy's gun belt. Bull bars in case it needs to shove you out of the way, hurrying to protect and to serve.
There was a time when the big three competed just for your monthly payment but for the giants wads of cash cops spend on their cars. I've owned a cop car - an '89 Chevy Caprice. The radiator was twice as thick as the civilian Caprice I'd owned before. It had a transmission cooler, an oil cooler, beefed up suspension and 5.7 liters of law enforcing thunder. That a picture of it right here.
Then the caprice went away, replaced with the Tahoe. How'd that work out? Dodge / Plymouth had stopped selling cop cars back in the 80s and cops, feds and narcs were left with the cop-killing Crown Victoria.
Chevy made a half-assed pass at cop cars with the front-wheel drive Impala. And it was sad. New York cops use these cause they're cheaper and they don't get into chases.
