Civic exi does 12-14km/l
Civic vti does 10-12km/l
City is a big contradiction, some say it does 18, some say it does 10. This model had new technology so there were serious issues with some of them
Lancer will do 10 km/l. But a lancer will be the most comfortable though requires a lot of extra care but still comfortable.
One vehicle that I missed out, is a 2001 1.6 suzuki baleno. amazing cars. difficult to find in good condition but a beautiful beast(a bit congested interior if you are of 6 feet or above height)
