Driving dynamics is a collocation from Benz world, no less.. Police Crown Vic is far more reliable than anything Daimler has cranked out since 1999.
Anyway, search for | P71 | Panther | CVPI | and you shall find a few nice boards with a lot of helpful folks. P71 has the same motor as the civilian CVic - that's a common misconception about the engine being in any way different. The suspension is different, the clearance is a couple of inches taller - you'll learn to recognise them from afar pretty soon, the transmission is nominally the same, but it is a heavy duty variant and much more durable than a civilian one, longer shaft btw - swap in pairs is easier, extra coolers for the motor oil and the ATF, heavier alternator. The cars with seemingly low miles have higher hour count, a lot of municipalities do hour counting on them, AFAIR one hour of idle counted as 32 miles, may have changed... The uptake/accelleration varies and is a function of rear differential gear ratio (there is like 5 of those, some with the TrackLok - limited slip) and a few other things. You will get the codes from the driver's door sticker and learn to read them pretty quickly. The car linked above seems to be overpriced, but if they deliver some added value in any way - why not. Those are 400k mile cars in brutal taxi cab business after the brutal police service. The downtown patrol cars may change their brake pads every 6k miles or even sooner than that. The CVPI usually have 'Police Interceptor' badge in the back. Some look like regular Crown Vics, yet they are cop cars - 'street appearance package', those say 'Crown Victoria' without LX in the end. They sit higher than the true crown vics. All street artists can tell the difference immediately.
Depending on the rear gear ratio you may get a great accelleration with the poor highway fuel economy. The best fuel economy I had was around 27 mpg on the highway and 18 mpg in downtown. Every model year has its fanatics that will tell you this is the best one to get

There are tons of cash'n'carry mechanics that cater to cabbies with good skill and for low prices in big cities. This is an easy car to wrench on, if you are into DIY.
Good luck
