@abdul_basit007 I will second @muhammad.irtiza.
Although i have been using mehran since 2016, and had done some mods with it also despite i hate it due to its ride quality and zero options.
i would suggest, u can go for an auto car especially japanese. the budget u have is more than enough to make it a daily driver.
Mehran parts are not best quality and they also need regular checkup or replacement. So far i have replaced its alternator, rack work done, suspension bushes, kamani serviced, fuel tank filler pipe replaced, belts replaced, wiper inner rods replaced, clutch/pressure plate+bearing change, clutch wire, some plastic bits and pieces etc. Waterbody is now due as it has covered 52k kms despite it has coolant in it and never used water.
the only benefit of mehran is that it has cheap parts and it can take u from point a to point b but remember "sasta roey bar bar and mehenga roey ik baar".
So if u want to go for a car to use as daily driver, i would suggest find an 660 cc alto vxr japanese inspect and replace the usual possible things like brakes, cooling system, fluids, etc and enjoy its ride as it is much smoother than mehran.
or if not an auto, then khyber is a good option. u can find a special edition in 400k easily and if us till spend 100k more it will be still beneficial.
but as irtiza said,
"Mehran is an excellent solution to a big problem - reliable basic transport.
If you are willing to sacrifice on the comforts of other cars, then owning one is a very rewarding experience."
