nobody will understand the point about consumables,petrol spares,maintanence... in future even X car companies will have some agreement with oil companies... to get percent share from the petrol/diesel sales consumed by there X vehicles..then tie up wid big garages again to get Y amount of profit for servicin or maintainence of there company car....kuch bhi ho sakta hain... then you may get cars for free in future...anyways TATA has done a great thing we have to appreciate him.
