if you want economy, do NOT think about Korean cars..
Mehran is good on economy as:
- car is light
- engine is small
- tires are narrow
- engine power is used to drive the car only.. i.e. Little to no AC, no power steering, etc..
Keep these factors in mind if you want to go for Mehran. Also know that Mehran is high on the stolen list as well. So there is always a chance of loosing it if not parked and secured properly.. The brakes are not so good, build quality is poor.. bla bla bla...
Otherwise, you can go for JDM cars as some of the small versions give excellent mileage with comfort too.. The decision is all yours based on your personal preferences..
Santro, Cherry, Chevy, Korean, Chinese, etc wont make the cut on economy... I have tried them all...!!
