Im pretty sure a diesel auto wagon i30 would be slower than a audi, after driving one i fould it a bit lacking, however this isnt for me, and my wife doesnt care. The 5 litre/100km is nice, however i would have to wonder if a landcruiser ran up the back of you, how would the kids go. Also an i30 is $19,990, by the time you get a diesel wagon auto, it is $31k.
