Unfortunately, there are very few sedan options available today, and between Rs 20 to 30 lakh, you would only find the Honda City Hybrid. The City will meet your requirements of good mileage and low maintenance cost, however this variant isn’t really value for money at all.
Thus, we would suggest you consider the Hyundai Verna instead. The car may not be as fuel-efficient as the Honda, but it is efficient enough.
We put the 1.5 litre turbo petrol auto through our standard test cycle, and it returned 10.76kpl in the city and 16.05kpl on the highway. The Verna is also well equipped and offers good value, and will be reliable and low on maintenance costs. It also secured a 5-star rating in the GNCAP crash tests.
