I think with Honda City body wise the 1.5 will give you better millage, I own 1.5 Aspire 16,and it makes me feel in control all the times,when you are overtaking the extra power will keep you in control,and the 1.5 handles this body weight easily so when engine is not in trouble you will get better mileage and most important how you drive,if you are considering to buy a car please go for 1.5,I dont know why people buy family cars in manual.
