Government wants more money

According to a story in The Nation, the Thai Excise Department are looking for ways to make more money.

Of primary interest to the motor industry is the possibility of a change in the way motor excise is calculated. The new system would calculate excise tax based on the retail price of the vehicle, rather than the "manufacturers price".

Now I could be wrong, but I would assume that this would result in higher end prices. If companies are now having to pay more tax (the whole reason for the changes is to get more tax out of them) and they still want to make the same profits, then retail prices will rise accordingly.
