Just wonderin but how much mileage can you expect out of a Duratec. I mean I know if maintenance is maintained and such you get a lot more miles but what's an average? Cause my car has 112,000 on it right now and there have been a few probs w/ the engine lately. And also, has anyone had an alternator go out on it? Mine went out about 6 months ago, I thought it was kinda odd because I had a thunderbird before that w/ 153000 and the alternator was stock and runnin smooth. But I was just curious cause i need this car to at least last me 3 more years.
