yes in Karachi cars are cheaper & clean, when i did not found any car on investor rate here, i send my friend khi he buy 7-8 cars there in 2-3 day then come back, then we sell them here 50/50 profit. we are doing this from years but can not trust any dealer thats why never get loss.
when we are in khi start getting call from dealers (idhar ak gari hai udhar ak gari hai) but 95% cars thek nai hoti, to apni samjh se buy karty hen.
if you do not able to go yourself then dont buy car from khi.
