Brother if you have long daily travel and go to areas like M.A Jinnah Road or Saddar congested areas 2007 Passo is best for you.
In local cars you can get a 2009-10 Cultus VXLi with power steering for 850K but its like a go cart and no comfort at all.
If you need a proper sedan with trunk for family you can get a 2007 XLi or 2005-07 Altis Auto in 1M, also JDM X Corolla 2003-05.
Stay away from Honda at all costs they have expensive parts and 5-7 years old used Hondas are pain in neck and not reliable at all.
2006-08 Vario (No CNG) will cost you 800-825K with around 75k to 100K mileage in genuine condition and repaint car for 750k. Manual City in which CNG works is 50K expensive.
2004-06 Civic Prosmatec will cost you 800-850K in genuine condition and 750k for repaint.
If u can stretch h your budget a little you can have a 2009 current shape City for 1,050,000 which is only good Honda available.
