Dear Nani

You can do masters in Automobile side. What I want to say is if you've already taken the gate exam it would be easy to pursue that course in IITS/NITS. if you haven't there are so many private engineering colleges are providing that course but it cost so much.

If you have enough time,  I would like you to suggest go to Germany to pursue that course and also you need to learn German.  This is the best option you've because it is the mother hub for almost all automobile industries.  If you pressure higher studies their, you cab continue your career in automobile itself.

All the best.
