I've driven Crown Vics (and variants thereof) since I first got my license in 1987. There's a good reason for my loyalty: Vics do everything well. Take reasonable care of a Vic and it will last forever; abuse it and it'll still do 250K easily. My current Vic is a '97 with 140K and my friends don't believe she's that old - she still looks, drives, and smells like she's fresh from the factory. Summary: best cars ever.
Smooth ride, very comfortable, outstanding safety and reliability, and the legendary 4.6L V-8.
Long reach to the stereo due to the wide cabin. Economy (17/25) could be better, but what do you expect from a 4,000 pound V-8?
