Car Issues - Again

When I went out to the car this morning to come to work, it would not start.  I turned the key and it just made an ominous buzzing sound.  Drat.  Just had a new battery put in it, so I'm hoping that there is just a loose cable or something simple.  Maybe I will get lucky and that's all it is.  If not, then we have to decide about whether or not to fix it or get a different car.  This one is almost 10 years old and has 183xxx on it.  I was wanting to get it through this winter, at least.  We also put two new tires on the front a couple months ago.  Ev's going to look at it when he gets up.
