Welcome aboard Nikhil!
It really feels good to see one more person getting interested into the world of rallying.
To get into rallying, I would advice you first get started as a spectator. Desert Storm

is definitely not for beginners. Firstly, get to know about the kinds of rallying, like endurance rally, TSD rally,... Then meet, make friends with the people who are organizing & those who are participating in rallies. It would be better you enroll into a rally school & have on-board (in case of 4w) experience. Finally gift yourself a rally bug & get on active. At least this is the advice I got & am following for the sake of rallying (I am still a spectator;).
Those Spark & Innova would be greatly helpful to move kids & your people around

, preserve them for that.
