The only thing is the throttle body had to be cleaned twice during the past 5 years.
I have been shocked at how good this car has turned out to be. I drive the wheels off of it and it has never failed me.
It is very comfortable and efficient. I have never gotten worse than 23 MPG, but usually average 25MPG.
It's not a Porsche or a BMW 750, but for the money it is incredible value... these cars are getting somewhat of a celebrity status with the hotrodders too. Read Hot Rod magazine or Car Craft and you see them mentioned routinely... too bad they've stopped making them for the common consumer.
Yes, the EPA ratings for a '99 Crown Vic were 15/22 mpg, but you get 25 mpg?
I don't care what the EPA guidelines say. As I said in my earlier comments "you have to know how to take care of a crown vic... but also how to drive one to get the best MPG. I just came off a 2 day road trip. The second leg of trip - I drove 426 miles and filled it up with 16.42 gallons. Use a calculator if you have to but... it comes to 25.97 MPG.
