In my opinion 660cc cars are meant for home use grocery car. School pickup.
These cars are not fit for commercial running. The careem/uber 660cc cars struggle to climb the smallest of the bridges.
For such Pakistani WagonR does the job you can replace the car every 12 months in hardly under 1 lack. Or else at least look for a toyota passo
The car saves aproxx 2000 plus fuel daily.
2000 x 25 = 50,000
50,000 less driver 25,000 less 10,000 car maintenance and replacement cost. (120,000) annually.
Net saving comes 15-20,000 a month. If you drive the car your self you can save around 60-70 thousands a month. And less all other costs replacing the car etc.
