Hybrid Cars are really good..
but the economical benefit depends on the way you drive it..
if u are a petrolhead who usually wants to go bit faster than usual and normally exceeds 80 kmp/h then there will be NO saving relating to fuel economy..
Instead if u r a normal driver who usually does between 40 - 60 kmp/h the fuel saving would be impressive..
But on the other hand Corolla Axio is also a really great car, which has a very good market value.. & it's one of the most reliable cars in the world..
Yes.. there is some issues with the battery in Prius/Any hybrid coz the replacement cost is so huge..
but in a corolla U can get both fuel economy & spacious, smooth ride at any time..
So decision is yours..
It depends on ur Driving style & the requirement..
