Should I get a 2007 civic si, Civic ex, Jetta SE or Wolfsburg, or Mazda 3?

My wife and I just found out that she is pregnant, and will be due in November. I currently have a 2 door coupe Honda Prelude. This is not exactly a car for a family....soooo....I am looking at getting a nice conditioned used car, certified if possible. I like all of the cars listed above, but which one would you get and why? This car is going to be my car for the next 5 years, God willing. So please let me know which one and why (good reasons). Thank you for your help, obviously I will take your suggestion into great consideration but I will still be doing test drives and everything as well. Thank you.
