If it's a '06 model fresh import, it'll be for around 14,00,000-14,50,000. Original Tv/Navi/DVD player and built-in CD player model's vary.
The depreciation thing is just a trend here in Pakistan. Even before buying a brand new car for there own, everyday usage. The person ask's: ''Iski re-sale kiya hai''? If you want to buy a car for your everyday usage and you don't plan on changing it within a year or two, I wouldn't suggest you buy it for a re-sale/profit point-of-view.
Considering the fact that the import duty rate's are climbing up and up day by day. If, you want to buy a car for a investment point-of-view I would suggest you start with car's that sell really quickly for good money, in the market or through private parties. Buying a car that isn't that well-known in the market and then trying to sell it for a profit would get you nowhere.
