Congrats Paul! Ours was due aug 24th as well (although he was early on the 12th!) What did you get in the end? Or are you still looking?
I'd suggest an Audi RS4 Avant (I personally prefer the older B5 model). Or if you want to be a bit different, a Mistubishi Legnum VR4 or Nissan Stagea
Practical, tons of room (all estates) for baby paraphenalia and a bit rapid!
