Truth about honda amaze

Buying experience was very good as the sales department makes a big deal about it. the car is ok to drive, but the there is a lot of engine noise in the cabin. if i talk about mileage my car gives anything between 11 to 15kmpl in the city which is very less considering this as a diesel variant.honda is really careless if you talk about service. we had to get the radiator changed under warranty as it started leaking and my car is just 4 months old.
