Can anyone help me out with the best used cars under 5 lakhs in Indian market?

Since most of us here are not in India... no. Plus with used cars you would be buying local to you.. not from the far extremes of the country because of the time and cost to get one from far away almost always exceeds any savings of a really good deal.

And even then. While some cars are more durable than others....the far more important factor is how well the car was taken care of and driven and maintained by the previous owner. Something that usually is unknown.
