Cars Q&A

I want to buy a second hand car within 2.5 lacs to 3.5 lacs. I have zeroed down to Swift and i20. The car I am looking for will be 2011 and above and less than 50k driven. Can you please suggest, which one will be the better option. My major criteria is fuel consumption (13-14 kpl) and low maintenance cost. Any help is appreciated
