I bought a gently used white 2001 Mercury Grand Marquis for $4000 last month. Still has new car smell. Has 53K miles. Interior nearly perfect, leather seats. Dark tinted windows. Added a 40'000 BTU trans cooler and coil springs. New tires shocks etc. Now I'm nearly $6K into it,insurance is 240 bucks a year. Looks like a cop car. Gas mileage sucks, 19 city/25 hiway. Power everything...even power adjust brake and gas pedal. 4.6L V8 with overhead cams and fuel injection is easy to service and plenty of parts available. I wish I could have found a Crown Victoria Police Interceptor with low mileage...but you can't always get what you want. The alloy wheels are made in Italy. It sold for $27'000 in 2001. I have the original window sticker. I see a few low mileage on Craigs for twice what I paid, the newer ones are flex fuel. Not sure if I made the right choice, but I really like driving it. Now if I can just find some body armor plates for it...and maybe a rack for an AR!
