Assuming yr talking about Axia AV vs Myvi 1.5X both ard 50K right?

If you like accessories & safety gadgets then AV.
Else the 4-pot 1.5l engine offers more options when you need it, eg outstation travels. You never know suddenly company transfer you? Etc

However if strictly urban drive point A to B, perhaps the Axia X at 40K might be actually sufficient.
