@baqai:
thank you bro for your kind concern, i have test driven passo & swift, passo is slightly better but there is not a big difference between both the cars..
i know few of my friends & specially my cousin who owned jdm cars like vitz, passo & premio. at first they had checked/verified their cars with many experts but after few months of buying jdm they got to know what probs cars had.. i know one dealer who lives near my place he imported a mitshu EK Wagon for his family use, according to him he couldnt find anything bad about it, but after few weeks he get to know left fender was replaced/repaired. His close friend (in japan through whom he imports cars) had done fraud with him, i dont know if dealer is not experienced or he believed his friend with eyes closed!
my cousin with premio had replaced back shocks & it costed around 28k (i think) & he found them after too much khuwari & waste of time. and many friends of mine said all jdm cars have a very common & big problem "stolen body parts" while parking! specially side mirrors & back viper.. even wheel caps are stolen as well 
baqai bhai i am totally with you, you are right trough out, i dont have too much time for all these khuwari stuff & dont wana waste my money as well, your reply is really helpful for me.. thank you!
