When I first saw the crossfire back in 2004 it was the car I wanted, but at the time I wasn't long out of finishing high school and my income was short of being laughable. Fast forward about nine years and I almost forgot about the car I once considered the best thing on four wheels until I witness one drive by. After that I went into finding one to buy now that money wasn't holding me back.

After some weeks I found one I liked which was not sold it before I called. A 2004 coupe with just under 51k miles. The price was a little under 10k so I considered it a decent deal. The owner was an older lady that practically did nothing for it except the standard oil change. I already replaced the original air filters and cabin filter. The battery is the one that came with it so it's going on 9 years old. It still works but is it a good idea to go ahead and replace it?

I've lurked on that how-to board for so long I just about confused myself on where to start in replacing 9 year old parts that might go bad.
