Chicago PD checking in here, and I did a short tour in our Motor Maintenence division a while back, so, the numbers may be slightly stale since then.
The fleet is just over 8000 strong, and 98 percent Crown Vics. The oldest is a '94 still in service for mail runs.
Every car has mobile PDT docking, your car keys are your personal computer...Screename and password, please?
The base patrol units are white when delivered through our Illinois "state bid" program that insures all cars are standardized. The base vehicle costs the CPD around 23K, and once fitted with all the necessary equipment, a fresh patrol car reaches about 28K.
Not all patrol cars get the same equipment. Supervisors get push bars, weapons racks, first aid kits, floatation devices, but no cage. Beat cars (I love that term) get all that, plus cages and LoJack. Beats that border suburban jurisdictions get ISPERN point to point radios.
Speed tracking is Traffic Division only, portable lasers. BTW, we still use some very old (and therefore sneaky) technology in some secret places. If you're Valentine 1 says you're near a fast food drive through, slow down?
Police in Chicago are exclusively blue lights, except airport cars, which are red. LOL, imagine a Cessna following an airport car into a Dunkin Donuts!
Just over half of the fleet is unmarked units, solid darker colors, just in case any of you hippies are wondering what our secret police drive. BTW too, all police cars display Illinois police plates, green on white background, starting with the letter "M". Ummm...So do all other city vehicles, like Streets and Sanitation, Department of Human Resources, Board of Ed, and so on. Only Police Department executives have their own "passenger car" plates.
We have about 500 covert vehicles spread out in special assignments, like IAD, Narcotics, OCD, Vice, and so on. Cars and trucks of all shapes and sizes, mostly confiscated vehicles used until they wear out, then they go to auction. Plain plated, and some may bear Illinois "TRP" plates, cardboard temporary registration plates issued when you buy a new or used car. The real serious covert cars for real serious undercover work, are daily rentals of any description.
We have XXX SOAR cars rolling about, I can't talk about them. But I can say they are non-descript police cars, and very, very deadly.
We use "paddy wagons" here too, large custom built transport bodies that are recycled from frame to frame as power trains wear out. Each body is divided into special areas for transporting women, men, juveniles, and dead bodies. Right now they are using those F-350 power stroke thingys under them.
We have two "RV" like mobile command posts and I've taken a dump in both of them just because I could. Also, two "TV" like mobile broadcasting trucks in Johnny Cash trim, with those big stick antennas in the middle that make them look like high cube hor'dervs when they're erect.
We have 50 or so 4 wheel ATVs for lake front patrol, sadly, our 12 Harley 'Electraglides in Blue" are ceremonial. Officer killed in the line/Presidential escort only. No "Chips" bikes on patrol...(pouting)
If any of y'all visit Chicago, you won't see everything you're expecting to see, until you call for help. Then, it's like Flash Gordon time yah, when Clay people are suddenly standing next to ya...
Weird, ya know?
