Beware while booking through Savari.com. It does not provide any dedicated taxi service but connects you to one of thousands private taxi owners. We recently rented a taxi through them to go to Rann of Katch from Ahmedabad. The owner/driver was very arrogant and at one stage he started screaming and shouting at my wife when she told him not to use his mobile while driving at 100 Kms an hour on highway.
During three days with us his mobile never worked and he inflated the mileage to claim more from us by using his car for others while we were at the Rann. Like Uber of Delhi Savari.com does not have any control over the taxis you rent.
