Around here we just got one of the Hemi Chargers and a V6 Charger. Ive seen the Hemi and some told me they saw the V6. I must say they look pretty sweet for a cop car.
Also about the Crown Vics, there was one that raced at the track with the light bar and all the other stuff on it and it ran like a 15 or 16 sec 1/4 mile.
bad part is that they are both completely unmarked and one of them has an NHRA sticker in the back window.
Crown Vic police cars = SLOW
Hemi Charger police cars = FAST
Mercury Marauder = Nice car, fairly fast, lame bottom end power but easily modable.
'94-'96 LT1-powered GM cars (like my Cadillac FTS) = FAST, SMOOTH, very modable.
