A newish Mehran would be fine I think. It slightly depends on what you are looking for in the vehicle too. Time factor does make a huge difference, the older a car gets, the more workshop visits it'd require.. i'd suggest go for a Suzuki or any other local brand (for the reason of spares, maintainance,etc).
Unless, ofcourse, you're a race enthusiat or something of that sort, than you can choose something more sporty or cool.
Good luck.
