The Maruti Suzuki Ertiga is a safe and reliable 7-seater MPV, and is expected to be very fuel-efficient too. We’d also recommend you try the Kia Carens Clavis 1.5 Petrol. It has a slightly more upmarket interior, more features, and better cabin space compared to a Maruti Ertiga. The HTE O variant is well-equipped and should easily fit your budget.
