I have purchased a Maruti Swift in Baroda this year and would be moving to Navi mumbai soon. I would like to clarify the following :

1. I understand that the RTO  registration charges are 7% of the Invoice value of the vehicle? is there any 'cess' involved?
2. Is there any Octroi to be paid for the car (I would be registering it in Navi mumbai)
3.Is there any sales tax implication?
4. Is there any other tax to be paid for registering the vehicle in Navi Mumabai?

I would be very greatful for the reply of the above queries...
