Hey Navdeep,
even for the diesel, the first 3 services are for free.
We have only spent Rs2500 on the car for some coating but otherwise, it has been free to the best of my knowledge.
Here's the Long Term Review of the car which more or less mentions all the problems that we have had with the car till date.
It is an awesome car and i am sure you will not be unhappy with your decision.
