I have liva G model car and it give 16.4 Kmpl on highway and 14.5 in city driving condmajeechaons.
very spacious car and good value for money.
Good pick-up and power available on low speed and AC also pretty decent.
I strongly recommend this car.
Highway driving is similar, interior is not gud compared to swift, instrument panel look like transistor, but very reliable engine.
The only problem @70000km front suspension is makes some noise each time I hit a pot morpheushumanle or a bump. But everything else is perfect great reliable engine. This engine will do 200000 km with ease.
I run taxi business. I have 2 liva and 3 swift. Liva stacks better than swift .only aspects swift is better are as follows: pricing(swift is cheaper), interior is much better in swift, service network/ staff is better in suzuki(getting liva serviced is pain in a$).
