I purchased my 1998 Crown Victoria from my company's fleet dept. The headliner needed repair, I put 4 new Michelins on it, 4 new shocks and replaced the seal in the rear diff. After a couple of fuel treatments, it was ready to go and started with 150,000 miles on it. The mpg on the highway was 24 mpg and city was 22.4 mpg! I use regular gas, drive pretty consistently and a lot of it on the highway. Most of the reviews say highway is about 18 but I have measured every tank and I am getting just under 25 miles per gallon highway. The car is quiet, responsive and has a clean car fax. The engine is strong and I oil changes every 3k miles but 6k miles on my Toyota.I will buy a new Vic from Ford.
I am just shy of 7' and love the room, the trunk is huge, the engine is pretty powerful and the entire car is stock!
The new Crown Victoria's have a more powerful engine, side airbags and ABS, better interior comfort and I will buy one from Fordfleet.com in a couple of years.
