I have a Wagon R which is really comfortable for a family of four but if there are 8 people, then we need to adjust.
It is good on road, especially on highways but a little bit cranky on cranky roads!
Fuel consumption is average, better buy wagon R on LPG. But this car is not very much comfortable for people who are taller than 5’5 or a little on the healthier side due to the fact that it will be difficult to adjust the seat and the person sitting behind will not have comfortable leg space. It is ideal for families of 4.
