Almost none of them are sold to private citizens. Full-size turnpike cruisers no longer earn much of a market share, and for those die-hards who still want one from the Ford Motor Company, the Mercury Grand Marquis is the same car in fancier clothes for about the same money, so it mops up the private sales. Which makes private Crown Vics rarer than red Rolls-Royces, so the subliminal response when you see one that isn't taxicab yellow or black and white with Police all over the doors is to think it's an unmarked detective's car. Or government issue of some other kind, maybe U.S. Marshals, or FBI, or Secret Service, or a courtesy vehicle given to a medical examiner or a big-city fire chief.

That's the subliminal impression, and there are ways to enhance it a little.

In the empty country halfway to Abilene, the tall fair man pulled off the highway and headed through vast fields and past dense woodlands until he found a dusty turn-out probably ten miles from the nearest human being. He stopped there and turned off the motor and popped the trunk. The small dark man heaved the heavy valise out and laid it on the ground. The woman zipped it open and handed a pair of Virginia plates to the tall fair man. He took a screwdriver from the valise and removed the Texas plates, front and rear. Bolted the Virginia issue in their place. The small dark man pulled the plastic covers off all four wheels, leaving the cheap black steel rims showing. He stacked the wheel covers like plates and pitched them into the trunk. The woman took radio antennas from the valise, four of them, CB whips and cellular telephone items bought cheap at a Radio Shack in L.A. The cellular antennas stuck to the rear window with self-adhesive pads. She waited until the trunk was closed again and placed the CB antennas on the lid. They had magnetic bases. They weren't wired up to anything. They were just for show.
