you should spend a weeks time atleast in karachi with these cars
and let some family member or showroom guy take care of these for you, Obviusly they will purchase the cars at investor prices but thats their job and thats how they make money.
A major thing to look out for is that the cars get transfered for ownership, You should get rid of these cars before the biometric system kicks in Sindh, Else their is going to be alot of paper work.
a good Honda City 2005 should fetch 1.2 to 1.5 Million depending on condition, 2006 + cars can get 1.6 million too.
A good 2007 Honda Civic should be anywhere between 1.5 to 1.7 million
these are just my assumptions.
investor prices means atleast 200,000/250,000 under market value for each car, Which might included repair, polish, to bring cars to bling bling condition to sell.
