[Help] I recently bought my first car, a 2003 XTerra, and have a few questions.

Some background (If you care) I bought the car April 21st, with 141000 Miles on it, but the engine was rebuilt. I bought it for $2750 and recently sent about $700 for a realignment, skid plates, and sway bars. We basically rebuilt the front-end Steering.

Not that any of that has really anything to do with what I have to ask.

What kind of music files does it support? (If I burn a disc of songs that I have bought, as MP3 Files, will it play them?)

What kind of Gas Milage will I be getting?

How long should this car last me? I'm currently 17, and want to make it last as long as possible, considering how expensive they are.

What would be my range on a full tank of gas? (19.4 Gal tank)

And If you can think of anything I should need to know as a new driver on the road, please help as well. Thanks.
