OK, that's pretty sharp looking livery as it goes, I guess. However, the term "Police Package" usually implies that the automobile in question has been specifically built for the demands of patrol-type use. This would include, but certainly not be limited to, a heavier-duty suspension, tires, brakes, and everything Associated with the car's undercarriage, a heavier-duty cooling system, a heavier-duty electrical system, including a high-output alternator and high-capacity battery to drive radios, P.A. systems, lights, and sirens, an interior made out of materials that can withstand the wear Associated with police officers entering/exiting the vehicle repeatedly, etc. These are just a few of the things I can think of at the moment, but I'm sure the list can go on almost endlessly. That "security company's" Corolla CE is nothing more than a standard CE with a striping and lettering job; the automobile itself is no more capable of serious patrol duty than any other Corolla. Sure, it would be adequate for patrolling a shopping mall parking lot, but that's about all it would be good for without at least some basic performance enhancements. Keep in mind, I'm not talking about making it go faster, I'm talking about making it able to withstand being worked harder.
You want a serious police car package? You'll be much better off starting with a Crown Vic.
