I also saw a couple of iO's here in karachi during last week, they were 2002 models.
seemed marvelous in looks.
Rumors are the duties are going to drop down in coming government budget (june 2009) plus the permission for 7 year old vehicles will be allowed to be imported,
Prices will surely drop down by then.
Right now, a 2002 mini pajero costs more then 500,000/- here in karachi. it used to be 4+
I am sure the iO will be available within 6 to 8 K after june.
