The sole purpose big mehran was cheap as chips wheels... Na heck we love pakistan, the box costs 0.9 Mil used...
Older mehran with the slant dashboard (had speaker in it) was much better quality wise... The car was heavier too... Newer ones are more for the sake of a new car not a car to be kept for like 10 years..
EFI engine can be installed in the older models too... At least I would do that, make a sort of derelict, install dampers at the back and remove the leaf spring and have an efi engine...
