Thinking of Buying a Yaris, Help Please!!!

[Just Do It]

Hey everyone, I'm new here so nice to meet everyone. I'm interested in purchasing a new hatchback and I'm torn between the Yaris, Versa and Fit. I'm on a tight budget so it looks like I'm more likely headed down the Yaris or Versa route. Also, the reason I'm looking now is because I want to take advantage of the Cash for Clunkers program and hand in my old clunker for $4500 towards a new gas saver!

So I know what most of you will probably say, considering this is a Yaris forum, but what do you think in the battle of the big 3 in the hatchback market (Yaris, Fit, Versa)?

Also, I'm tight on money as I'm going back to college so how much could I realistically get off the Yaris MSRP? I really like the 5 door S Yaris which carries a $15,500 price tag.

Any other comments, suggestions and opinions will be welcomed, thanks in advance!
