Bhai, whats your budget for modification.
Please let us knw the model and shape by posting pics.
new shape bumpers doesn't look good. old shape bumpers give a better clean look.
if u have budget, then u can get Japanese mehran bumpers, back diggi spoiler, bonnet air intake and door kits from market like shershah in khi and bilal gunj in lahore.
let us know the budget and the pics. you can also see below thread done by me .....some of the mods to my taste.
