i would again ask u to share the source of ur news indicating towards increase in sales tax/FED for small local manufactured cars specifically.
Govt makes policies and subordinate departments implement it in economy.
Overall policy is clear that govt is looking to reduce import bill and will make car imports (which is very small part of import bill) expensive by application of certain duties and taxes, nowhere it has been mentioned that duties/taxes on 'local manufactured small cars' shall be increased while it has been reduced recently in july and havent been implemented 100% as some are still waiting for the refund of sales taxes and FED.
noone is so naive to change something which havent been implemented and closed 100%.
aparts from above, there is something called Law of negativity, which says if u think negative then all negativity will come towards u.
