Well in the price of vitz you can get a Hybrid car Honda Fit... way way way better than Vitz in all aspects...
Now Faw V2 is good and its a market car it has all the options those are needed in the car... after sale service and warranty all that you will be getting with it... Its a local car and better than any Suzuki car in its price range...
So if you are looking for local car then Faw is the Best in that price range and options and safety...
Now Mirage is a imported car and its new in PK JDM market... There is a little bit problem of parts but you can import the parts... Also you can get some from Bilal Gunj
Car wise and fuel economy and options wise i would say Mirage is way batter than Vitz and Faw V2...
Mirage is the same as Vitz is durability and quality in less price with more fuel efficient engine.
Mirage is the best in its price range...
This car performed very well even on bumpy rough roads and even in hilly areas and Alhamdulillah no Mechanical or any other issue so far...
Its best in Fuel economy... Non hybrid car.
Car running cost is low...
Air filter oil filter are easily available in the market...
