The Premium amount on GLI is around 60 to 70 thousand, any color. As a test case ask Motor Mania to sell this car, immediately. See the reaction. The dealer will NOW tell you the REAL ON.
As regards to CNG, One is CNG Complex at Pindi stadium. Other is Rawal CNG near National Market. Cost with regular fitting 47500 and with so called "executive" fitting 49000. Lendi Renzo EFI kit. Get the Influx 55 Kg cylinder because EKC is heavy in wieght (about 15kg) than influx. Best cylinder is Faber but the cost is toooooooooooo much. Emulator and advancer would also be part of kit.
But I am surprised at the ON amount. You have fooled by the dealer. Should have done some research. Anyway, now enjoy the ride. By June the premium shall come down to 15000.
