i would agree with all of your first statement...they're used heavily,but at least well serviced and repaired when necessary.
as for the standard crown vic police special used by 99% these days...they DO have a special equipment package,heavy duty suspension,lightweight aluminum driveshaft etc,a quick google search should turn up most all the details pretty easily..they also have a bare bones interior and these days the chip for the fuel injection mapping that gives em a bit more juice has likely been pulled and replaced with a stock one prior to sale...tho you may get lucky there
There is NO "Police chip" That is in fact an internet/urban myth....The Crown Vic/Grand Marquis interceptors have a completely differnt computer tune, larger MAF sensor, and differnt air intake. The only "Cop Chip" you may find is under the seat, if one fell out of a bag of potato chips
