2005 Ford Crown Victoria LX 4dr Sedan (4.6L 8cyl 4A)
Bought new in Sept 2005. Had every option available for the LX, and was over $30k. Got a really great deal and have loved the car. We live 45 miles outside of DC and average 22-23mpg mixed driving, and 26-28mpg highway.
You can ride all day and never get tired. Very smooth ride. Use the cruise control on the highway or you will find yourself going well over the speed limit it is so smooth and effortless.
It still amazes me how much you can get into the trunk. At 21 cubic feet, it is huge!
If you can find someone willing to part with theirs, buy it. You won't be disappointed.
