Mukang gas consumption talaga habol mo, get the Yaris... Its kinda boring to drive and very numb steering but it gets great gas mileage... The old Jazz is also good in CVT form kaso mas medyo sensitive ang CVT ng Jazz GD so I still suggest the Yaris para iwas possible headache...
Forget the Civic, siguradong talo yan sa fuel economy against the Yaris and GD Jazz... I own 2 of the 3 cars in the list by the way (Civic FD and Yaris)...
