Tata Indigo GLX Vss Santro Hyundai

HI i was planning to own my first car, and was perplexed between the two santro or a tata indigo cs. I have finally settled down on indigo cs. The car is good with its interiors and definitely is far superior than the later, i think i had by far made a wise decision by switching to a tata car. First of all the car gives you a really luxurios look with spacious interiors and makes the person turn their heads on road. Since this was my first car i had taken some time in learning to drive with this, so had engaaged always in the first gear, due to which is eating upa lot of petrol i guess, its giving me a mileage of only 8, without ac on : (  Hopefully  it should be getting better once i am having my first service free done.
