This car has been great. I have about 135k miles so far and no really major problems (except one, which I will talk about later). I have gotten 31mpg on the highway and I usually get around 21mpg city. Had a problem where the car was mis-firing up hills and when the engine was under load. Did some research and figured out it was a bad spark plug cable. Replaced all the spark plugs and cables and now she purrs like a kitten. My A/C compressor clutch died about a year ago now and makes a grinding noise every once in a while, but that doesn't hurt anything or effect the car in any way (although no air conditioning, obviously). Driver power window just died a week ago. It's an old car, though...
I bought this car a few months back from a friend. It has 189,000 miles on it. I bought it with the intentions of putting a new motor in since this was neglected. 20,000+ on oil, 30,000+ on filter and 3 quarts over full!! I decided to drain the oil, give it an oil change and filter change, drive about 50 miles and redo it again. This car is great. 29 MPH on interstate and no check engine lights so far. I have to tell you, with that much neglect and the thing still gets great gas mileage and never fails to start...there is nothing that I can do to that engine that will harm it!
I bought mine from a friend when it had 180k miles, but sadly, it already had a lot of wear, so I can't be sure, but I think it was just driven really hard. I've had to replace many parts, including the radiator and transmission, but the engine just keeps on going. Unfortunately, it still has a few different leak problems that I don't feel like spending money to fix, so I'm driving it to the ground and getting another car.
I drive this car 7,500 miles/year and I'm glad I don't have to spend any more time in it. The leather seats are uncomfortable after more than 1 hour. At 60k the transmission started to hesitate on 1-2 shits. Trans. still working at 86k, but wondering how much life is left. Have been plagued by constant A/C issues. Some stupid little plastic part that controls where the "air" comes from is now on its 3rd replacement. Nothing like having the drivers side getting A/C and the passengers side getting heat. I have now replaced all 4 power window regulators...twice. Gas mileage is not great. 14 city/21 highway. My Crown Victoria was a much better car.
