Brother sincere advise do not jump to vitz directly from mehran.
first buy a 2008-09 model new shape corolla xli or 2007 altis auto or 2010 swift DLx to get an idea of car maintenance.
also u can buy new shape vitz 2011 model in future which is available for sale in karachi for 1.4 millin.
If u wnat to get a vitz anyway look for 1.0L U grade vitz with low mileage 2007-08 model will cost u around 9 lac.
1.0L engine is best for city use 1KR Fe award wining engine 1.3L wohi purana corolla wala crapy eninge hai stay away from it its heavy thirst and expensive.
2010 ki gol igt wali new passo bhi 11 lac mein mil jaye gio better than vitz.
