Welcome.
Nice to see that there is more life in Adelaide after all!
My only comment on your choice of car (and we have both Barina and Astra) is, to look around and see if you can't pick up a low km Astra for the same sort of money as you would be spending on a Barina. With the release of the "Classic" Astra and the new model just around the corner (November I've been told) the price is bound to drop in the 2nd hand stakes.
