1) pollution is addressed from road tax. thats why 3001cc diesel
is paying ($3,050 + 2.0 x (3001 3,000) ) *6

2) COE is tied to market forces, means more pple buy, price go up.
apparently got alot of ppl buying 1.3L and 1.5L cars lately. thats
why go up.
3) Also the same reason no one goes for 2L cars coz the same ppl
wont be able to afford it. these are the same groups who take 10 yr
loans.
4) IMHO, LTA should give a different COE class to 1.4, 1.5,1.6 coz
i believe there are more < 1.6L car owners nowadays. thus making
it quite unfair to 1.6L owners.
but then again. this is sigapure.
