i hope that i got this calculation correct, because i've been trying to figure out how much tax to be paid if i were to bring a car back to malaysia with a student AP. (i want to get a rough estimation of the total tax to be paid before sending an email to MITI for final confirmation).

Car to be bought-

Nissan Skyline V6 3.5L 2007 (RM25k)

Engine displacement/capacity- 3500, 3.5L (i'm assuming that i'll be paying 175% for this engine?)
Age of car to be imported- 6 years (will be shipped on 2014, so assuming 30%)
Sales and excise duty- 20%
Appeal- (-30%)

So total tax to be paid- 195% (1.95*25k = RM49k)

is that a good rough estimation? or should i add any other justifications? i know that the road tax for this car is damn high.
