I beleive you have bought this car as a disposable appliance, because surely it wont be in good nick after 4 or 5 years of use in Pakistan. The OP of this topic posted about bad fuel mileage too, so please explain the economic sense of using a car which is completely alien, gutless, has super expensive new body finish parts like lights etc in any city of Pakistan. Your choice of car is your call, but in real world sense - buying a set of new headlamps for a corolla would be cheaper than buying a set of new lamps for these. Your entire (if true - because I could never get any from any kei) fuel savings will be burnt by such items.
The serious work bit, lets take a daily commute car whose job (aka work) is to operate without drama and hassle everyday to carry you to work and back providing acceptable economy and you follow basic maintenance just like any machine of the world.
It wont make sense to me that the car requires a check often and causes me to rearrange my life because of it and to top it with that I literally have to hunt for sundry spares.
As I always say - your money, your car, your game.
