Guys, If you want mileage of 75kmpl in economy mode, It is the HONDA Dream Neo for you. It has the smoothness, acceleration and characteristics of a Honda.
IT is a modern engineered vehicle and less maintenance needed.
Dream yuga and cd110 is also another choice.
They are called lean burn engines and can run leaner without giving problems.
But I advice you can tune a little rich for good experience and smoothness.
