Dont go for mira,, very light weighted and over priced. Your choice is very very good i.e. Nissan Dayz. but remember nissan is good for usage, resale kam hay.
Please visit https://www.sbtjapan.com/...ya japan say dunya bhar may cars import kartay hain and they have office in karachi also. Baki lahore ka nhe pata, ap un kay website par number hay wahan contact karain, they will guide you.
Either you buy from them (foran mil jai ge agar stock may huwi) ya un ko bolo, wo ap ki pasand ki car japan say auction kar kay mangwa kar dain gay (thori sasti paray ge ap ko) and invoice price plus commission lain gay...(45 days lagtay hain import may)
Baki, ap imported car kaheen say be lain, two things are must 1. auction sheet lain and match with car specifications such as chasis number and 2. auction sheet ko verify karwain japan say bcz yahan 2 number auction sheets are common.
