we have new mehran euro2 Vxr i am using it for my university .Milage is pretty good i am getting 19-21km \L in city without ac and with ac 18km\L ..Ac cooling is much much better then previous models but still you cant compare it with Jdm's..
If you are looking for resale value then go for mehran Vxr because i am getting full amout that i had paid for it after using it 6 month its mean my money is save.
Bro you have to compromise in many things like interioir,Drive,comfort,Sound system,Shocks,Che che chu chu like sounds while driving,poor insulation,poor brakes,no power steering...i am not here to hurt you this is my personal experience and still going through.
Conclusion:if you are really looking for resale value then go for it(mehran Vxr) and if you looking for luxurious driving then mira is for you..Hopefully you get my point.
