What car should I purchase? 3 Options?

Hello! So I'm looking into purchasing a new used car. I have the following choices:

2003 Infiniti i35 128k $5k.
1998 Acura TL 3.2 91k $4k.
2008 Ford Focus SE 115k $5.5k.

I know the Focus looks like the best, but it is also the most expensive. Would it be worth saving up a little more cash so I could get a larger down payment for the Focus?
