In karachi , Chevorlet Joy ky mechanic kafi kam hy aur parts b mushkil sy hi milty hy. 1000CC jo ky paki assembled hy wo to bhool ky b mat khareedna. Try to find 800CC japan assambled.
Vitz parts are easily available and this is also a very solid car. Remember its toyota.
Baqi I recommend you that don't go for CNG,try finding 2005+ Automatic or earlier then 2004 Manual Vitz. You can easily get 15 average in city drive. Agar rooz ki drive 30KM sy less hy to go for Vitz and no CNG in it. Monthly 1000 rupy ka difference pery ga sirf aur sirf airfilter aur oil change hi kerwana pary ga.
Agar achi gari mil jayee to parts ky masly kam hi aaty hy and you only need running parts like air/oil filter, tyres, etc. Kabi b bhool ky cheap gari mat khareedna, market value sy jo gari 5,10 hazar uper mil ri ho generally wo kafi achi condition my hoti hy. Aaisa hi koi peace dhoondna warna rooty reho gy chahy vitz lo ya JOY
