If u hv already got mehran then I ll advise u not to lease from csd. Its not csd but leasing from anwhere means burdening one self.
I ll recommend buying a car (nt leased) after u earn some $ on UN msn. In this way u ll get a car of ur own coupled with securing ur earning.
As far as gli vs city, tausif has guided u v well.
Regarding gli being underpowered, I happen to own a gli 2k10 n i hv taken it till green spot paf mess kalabagh with full load n it didnt disapointed me. Yes it ll not burn rubber like city on intial launch but other than that it is good. Till 150 it remain stable on motorway though it can go to 200 which i never tested.
Hope that helps.
