kamal karte ho pyare bhai. the suspesion design is the same. i agree. is part quality also the same?
NO. dont you think parts quality makes any difference? it does brother and the ride quality changes dramatically.
compare the suspensions of any model (imported and local). you will definitely find some upgraded parts in the imported one
we always get new shapes and newer models after they are launched everywhere else. why?
what about the PHATTA seats in local vigo? isnt there any difference between the seats too? seats dont change ride quality and comfort?
one of my very dear friends of PW got a pair of recaro seats installed in his mehran and asked me to test drive it. the mehran doesnt feel like a mehran now 
yesterday, i saw a daihatsu esse 2011 model onnly 6000km driven and it is GUARANTEED non accident. the poor owner is suffering a loss of 80k rs after import. the point is, there are clean imports out there and they run and perform just like any used car here. one only needs to sped some bucks on quality and forget worrying.
