a Yaris is a good idea.. a little 1.5 litre engine which is
pretty responsive (i know.. it's the same engine as my car)
but you get zero boot space so lugging back the groceries will
take the rear seats...
if you want to drive interstate, you should get something with a
minimum 2 litre engine.. the little 1.5 can make it but it'll be
taxing on the car...
I saw the online brochure for the Yaris and apparently, one can
collapse the rear seats to get a much larger boot space, which I
intend to do. I shall only be driving myself around anyways,
because I won't feel comfortable driving anyone else around until
my driving skills are good, which will take years of experience for
someone like me.
I'd
hate it if someone else got injured riding in the car I drove,
y'know. 
So, for one person, the Yaris is a perfect size. Don't
think I'll be driving interstate much, at least, I won't be
covering too much distance in a single day, because I fall asleep
easily, and don't think I can do all-day, all-night drives.
In any
case, if I DO take my Yaris for a drive interstate, I will want to
stop at idyllic countryside areas and rest in the B&B's and
take photos around the countryside. It shall be a lovely,
leisurely drive! 
Tonight, I just lugged home almost A$100 worth of groceries and
etc from Cole's.
Biangz...
imagine if I had a family here, die man!
