Oh. 
Road tax
Vios is standing at $437 (6 mths) while Jazz is at $400 (6
mths).
Insurance
Now that's a tough one. BM offers Vios with a package with AIG to
enjoy the rebate. General guide I have for this one is at 28 yrs
old, 1st car owner with 0% NCD, $1600++.
As for Jazz, I can't comment, but it should be slightly
lower.
Petrol
Jazz is definitely better in terms of petrol consumption. But since
I have no idea how's ur travelling habits, so I am gauging a lower
petrol cost based on Jazz. Maybe $250 and below?
