Totally agreed with the above. In case of filer, going from 1.6 to 1.8 CVTi Grande costs more than double of going from 1.3 auto to 1.6
(Base price diff.+WHT diff.+Reg. diff.)
From 1.6 to 1.8 CVTi Grande = 350,000+25,000+10,000 = 385,000
From 1.3 auto to 1.6 = 125,000+20,000+25,000 = 170,000
P.S. I am an accountant, so can't stop myself making these marginal cost comparison calculations
