Is honda city zx 2007 model a good car to buy?

I'm planning to sell my hyundai getz prime topend 2007 model and get a honda city zx 2007 model
Is it a good idea? I want more mileage.
Because my hyundai getz runs only 6.4 kms/L which is very low. So i thought of buying honda city zx 2007 which gives more mileage. Does it really give more mileage? Can i go for it?

Depends on how you drive. While cruising one would potentially save gas. However if your are the kind of person to accelerate from 0-60 in 2 seconds you most likely will burn more gas
