Another question. My dad's colleagues has been telling him not to buy a Honda car because there are not many service centers of Honda here. Which is true. Search the hondacarindia.com website for service centers and dealers in Assam. You will get the picture.

Even 6 months is quite low compare to Maruti.
In that case consider Swift ZXi
