I drive a Holden berlina s/wagon, we only have one kiddy
Pros:
handles really well for such a beast, I went from a zippy little Mazda 3 to this and the transition hasn't been as hard as I thought...very easy to drive
massive boot, just chuck in all the junk
lots of leg room
electric seats which is handy as DH is 6'6 and I'm 5'2 so I can make the seat nice and high to see out
cheap to repair (you can get generic parts rather than genuine)
very safe...Berlina has all the little extras like stability control, traction control etc
the quintessential aussie family car

Cons:
chews through the petrol...cost $100 to fill sometimes
can't get into those tight carspaces


we've also got a Mazda 3 which DH drives now.....I highly recommend them if you're after a 4 cyl
pros:
VERY efficient.....DH works in the city so 80km round trip, 5 days a week and a full tank lasts the week
big boot (the sedan one anyway)
hold their value well

not much to complain about with them really.
