I've had some experience driving ex-police cars...was a cabbie for a few years in my younger days here in Southern California. All of our cabs were from police auctions, and they were all fairly nice when they came in.
The Sheriff patrol cars were late '80s/early '90s Caprices at the time, with the occasional Dodge Diplomat from the CHP. The detective Caprices that came in were in the nicest shape, but were bone stock underneath while the Caprice patrol cars were a little more beat up but pretty beefy underneath; HD suspension and tires and faster than you'd think.
The real monsters were the CHP cars though. Those Diplomats had bucket seats, awfully stiff springs and swaybars, handled shockingly well, and would flat out haul ass. I got clocked one night at 127mph (and still accelerating) coming up the 5 from San Diego with a fare in the back. Luckily, I only got written up for 85 in a 65, but that took some fast talking.
