All of the pursuit models I've seen have the H.O. 3.5. Some have dual spotlights, most just single on the left. Also, all of them seem to have the rubber floor covering, no carpet. I have one that used to belong to the city of Bemidji, MN. It has about 134k on it now, had 82k when I bought it, runs and drives great. I had to put some work into it; timing belt kit with water pump, radiator, lower control arms, brakes, steering gear (leaking), front struts, hooked up the rear door locks and windows, and replaced the rear vinyl seat with a cloth one, and I put in an automatic dimming inside mirror and trip computer from a 300 just because. I'm a mechanic for the state of ND, and they had a batch of these in 2002. They were great compared to the Crown Vic. WAY faster acceleration, better handling, better fuel mileage, and the troopers that had them liked them better overall. One trooper they were gonna swap out to a Crown told them that he had 2 years to go to retirement and if they would take his Trep away, he would retire on the spot.
They didn't take it away.
The problems were weak brakes and they cost more than the Crown Vics, and the troopers were used to rear wheel drive. By 2004 they seemed to have the transmission problems solved and they were good cars... Then they quit making them!
I don't drive it much any more cuz, although they were good in their day, the just don't compare to a Hemi!
About 8k miles ago I drove mine to Lansing, Michigan, averaged 26mpg. It's a really comfy road car that makes everyone else slow down...
