Back in the early 90s, I asked a Southern California police officer why all of their new cars were the goofy-looking Chevrolet Caprice. Previously, there was a mix of earlier, boxy-looking Caprice, and also the Ford Crown Victoria.
He said that, by that point, the Chevy was the only model available with a “police package”. This meant a certain engine, plus a stronger wheel suspension, and stronger electrical system. There might have been a different automatic transmission system.
He called it the, “Shamu-mobile”.
