The maintenance costs are low since there are so many of these cars on the road still. For a big car it has a lot of pep and a very big back seat and trunk, extremely room yet not overbearing for it's size.

I find the performance is at the high end of rpm spectrum, it has needed repairs, but it has 165000 miles so that's expected. I love the way it looks, both inside and out. It's a bit of a gas hog, but you should know that with the 4.6 L V8. It is very fun, if you don't mind tight squeezes and people thinking you're 80 years old. Update- I'm up to 217,000 miles and it still runs like a brand new V8! So far I've replaced the air idle controller, mass air flow sensor, and the plastic (WHY FORD WHY PLASTIC!?) intake manifold. For a car that's got so many miles I don't think that's too bad at all.
