I will be staying in Delhi with my relatives and although they have a care I would like to be driving around myself in my own time without having to cause any problems in their schedules. I have thought the best way would be to rent a car in Delhi. It's been a while since I have been to Delhi so I am not sure whether there are any car rentals in Delhi so I need to find out and also know what kind of charges would apply.
In my opinion booking a cab for each ride would be better... These days Ola cabs in delhi provide quick and comfortable cab services...
OLA and Uber both are cheap and more or less the same price but they are both taxi service. If you want to drive yourself then get a car from zoom car, it will work out a lot more than hiring a taxi if you are planning short trips.
