Replying to Which kind of Subaru Impreza?

So I have finally narrowed down my list of cars to this.

But now the question is which one?

Problem is that my mom is only giving me 10000 so the rest is up to me I am looking at about 5000 from my part but less is always good.

I have been scoping around and have seen a 10000 2006 2.5i

Besides that there are no other deals around so, should I wait and what should i look for?
