If you have stock engine then it is Fuel guzzler in terms of Petrol as a Fuel but if you will convert into LPG then you can use Baleno easily in Uber/ Careem/ Bykea/ m-rides/ Indrive/ Yango etc.
Specially if you are in Karachi then you can register your car in A/C category and can earn handsome amount nowadays(Nowadays means Whole Summer season specially From and To Shopping Malls rides)
agreed with @Massive_One, This will give good mileage on LPG. Only condition is install properly as per safety standards and maintain your car in terms of Coolant, regular oil & filters change, working A/C, clean interior.
