Corolla for careem, I don't think so. I think for RENT A CAR, corolla will do great. A relative of mine in Karachi has two corollas on rent a car. For brand new car they give Rs.70,000/month and for one year old they give 60,000 but they keep car only for 2 years. You just have to give them car, no need to worry for fuel, driver, oil change. On that basis after around 2 years, you will get more than 15 lac return plus a car( it won't be like new but you can sell it at a good price probably around 18 I guess.
New GLI auto = Rs. 24,00,000
Total Rent = Rs. 15,20,000
Car Sell = Rs. 18,00,000
Profit = 15,20,000 + 18,00,000 - 24,00,000
= Rs. 9,20,000 in two years
But, do contact others before taking this step.
