Good car for new buyers /new learner's

The mileage is not as Par company declared. The city mileage is only 10 to 11km/liter, whereas in highway it is not more than 14. It is totally contradict to company's mileage declaration of 25. The space, boot space is very good. AC is also good. It always required to shift to the downgears example from 5 to 4 for the speed to boost up during overtake. Overall good car for beginners but company has to workout on cars mileage.
