I bought a 2000 Ford Crown Victoria Police Interceptor In April of 2008 that had about 57,000 miles on it. It was in great condition and was only $4000. It's great for family trips and real fun to drive. It has plenty of passing power and is fast off the line. The engine is very quiet and the transmission shifts quiet softly. Mine is Performance White and looks like an unmarked police car. Cars tend to move aside for me on the highways and people aways drive carefully when I'm around.
Intimidating cop look, very powerful 4.6L V8, dual exhaust, 3.55 gears, 4R70W transmission, stiffer(700 lbs./in.) front springs, and rear locking differential(posi-traction).
Since mine is a Police Interceptor theres a lot it could use especially for the interior: cassette, CD, or MP3 playing radio (only has AM/FM), center console or arm rest, carpet (has that annoying rubber matting), and a spot light (to cover up the hole in the driver's side pillar).
