Lots of room, very comfortable, gets me anywhere I need to go (on or off road) -- and with a cap on the back, I can even pull into a campground for a good night's sleep without setting up a tent!

The police love their cousin, the Crown Victoria. TONS of room, as comfortable as your couch down the road (you can drive for 8 hours and feel perfectly fresh), huge trunk, good power, and I get 27-28 MPG at 85 MPH between LA and LV, with four large (6 feet, 250+ pound) guys in it.
The best part is that you can get white rentals. People tend to move out of your way when you're in one, because from 200 yards away you look EXACTLY like a policeman.
