I prefer the "pre 1998" P71 interceptors. The body style seems a little
more streamline, and they weigh a couple of hundred pounds less than
the 1998 and newer models.
The Police Interceptors are built for severe use, and have heavy duty
components. You can expect at least 200,000 miles without major
problems if you keep them maintained.
I am a LEO, and drive both the pre and post 98 models. To me and
others the 1996 and 1997 P71's seem to have the best performance,
and the suspensions seem tighter and more stable at high speeds.
The Police Interceptors use the Ford 4.6L SOHC engines, and the
performance of stock units are very similiar. You can expect zero to
sixty times in the eight second range, with sixteen second quarter
