Q. Which Honda amaze model is better?

If you can afford, I suggest Upper variant as in coming years lower variant becomes outdated. Take instance of front Air bags. The new cars will have compulsory feature of front Air bags for Driver and co-passenger.

Between E&S Varianta S model is best .Between V and Vx variants Vx is better .Regarding safety features like dual front air bag, AbS+EBD , rear sensor , iso fix child seat and power windows etc are offered in Base variant like E .This is the best part of Amaze .So safety is always ensured.So every variant in Amaze is unique in their way

There are four these four choices: E, S, V and VX, and all four variants carry additional features one over the other .If your choice is for manual transmission then Top end variant Vx MT is the best option .
