There was a parallel world then shaking the foundation of these riches and their masters - British. But thanks to them India got access to cars meant for upper middle class - The mass produced cars of Fords and Chevrolet. By then Cars were made faster if not rugged than Elephants and our own political leaders loved to use them. There was no dearth of such cars - Indian businessmen, lawyers, politicians owned them. Our front line leaders came from this class of people. Educated, exposed to western world and its culture with a vision of their own for their own country free from the clutches of a western power.
Then came India's independence. Fortunately WWII gave enough impetus to mechanized growth that cars and trucks and jeeps were not for a few but became a necessity. Collaborations, Assemblers, Franchises in auto industry increased. Enough of used Jeeps of WWII saw a new market in India. Indian defense and its new administration needed a mode of transportation. A transportation that was relatively cheap and rugged enough to enable them to reach far and undeveloped places. They also needed better city cars rugged but sleek enough for the new leaders of Independent India.
