Sinicker...
Hope yr dad change his mind lor and go for the hatch instead
For me, reason y I chose hatch instead of sedan becoz
I'm quite tall myself (1.82m), so the height of most sedan cars dun
suit me, plus if I push the driver seat back to my comfy leg space,
the back passengers will suffer.
When I test drive the Yaris, both the driver and back space are
good. I like the interior, it's as spacious as the Altis 
But of course, the discount is at the boot space la. But I figure,
I dun need to put much stuff at the back, so not much of a problem
here. Besides, it's flexible and adjustable. 
Let's hope there's not much problem for this first batch of Yaris
from BM (fingers-crossed)
Cheers!
