all 660cc cars are under-powered touching 120kmph is a miracle .. even u get this speed then it is harmful for engine because of high rpm .. the space is cramped specially on the rear seats .. my neighbor has an Ek wagon and after a lot of struggle, he hasn't achieved 14kmpl in city, while another neighbor claims 15kmpl on a similar vehicle .. getting 15kmpl or higher varies from car to car so it is a luck factor rather than a fact.
if u are lucky a passo or vitz give the same mileage, but a drive and comfort much better, except for the acceleration otherwise it is even better than suzuki swift
either stick to swift or buy vitz but never 660 cc
