Sell the car, People living in Pakistan cannot maintain cars in different cities, 2 year in another country is a different story.
Wherever you leave it even parked, the car would depreciate in terms of alot things, tires, rubber, body damage bla bla, even if you hand it over to some relative it will be used. Better sell it buy something where you are going. Or simply keep $USD
Buy something when ever you return.
