We buy our police vehicles off of a State Contract. So yes, the contract has been awarded to the lowest bidder, however, it's not a contract with Chevy or Ford directly, it's with a dealership. Yeah strange. Anyway, we have Ford's... Crown Victoria for landside patrol, Explorer for airside patrol. There are special police packages which include several safety enhancements, different cooling system (since these vehicles are driven harder and faster than regular vehicles), enhanced engine, and different seats (plastic in the back, so it can be easily washed after an upstanding citizen has been carted off). In addition, once a PD takes possesion of a car, the department itself adds things such as the cage, window protectors, light bars, spot lights, radios (which in our case include a ground and air radio) etc. These cars are not cheap. And these cars are safe. I have a personal stake in them since my DH is a police officer.
