You have not specified which fuel type is your preferred choice, but if you want good mileage in 7 seater segment, we suggest you go for Diesel.
Since you are driving a Mahindra XUV 5OO, a good upgrade for you is the soon-to-be-launched Mahindra XUV 7XO. However, at 18 lakhs, you will have to choose the MX or AX5 variants, but unless Mahindra gives 6 airbags in these variants, it will fall short on the safety criterion.
A very sensible alternative is the Kia Carens Clavis diesel. It’s comfortable, practical, and well-suited to family use, with a ride quality that works well both in the city and on the highway. It should also deliver good mileage and is generally easy to live with day to day.
