3 doors does look better! but I just found out my wife is pregnant..
Congratulations mate! A nice Christmas surprise for you!!!

I don't have any children myself, but I do have a couple of mates with kids. Both of them have a second car with 3 doors and a main car with 5 doors. They manage the 3 door car fine, but it is more hassle obviously.
If I were having a baby, I'd change mine to a 5 door too... and spec the extra rear airbags.
