If you are planing for a self drive car service there are lot and Myles is one of them. But its a fact that I have used their service to travel mangalore and unfortunately it was not pleasant.
Its a shame to say that breaks of car were too loose and there is one instance where in rain breaks did not function at all and vehicle was in free flow fortunate that vehicle was in very less speed.other wise impact would have been very severe.
And reaching customer service is a big task, you need to wait for at least 10mins before someone attend your call, and local staff are irresponsible.
There are many other self drive portals, I would not recommend this.
