Zest (Diesel) is a better option over Dzire, its built quality, service schedule is better , riding experience is awsm till now i have drived 15k kms -in city i am getting the mileage of 18kmpl whereas on highway 22kmpl around.
Service Centers experience was satisfactory they take time but complete the job with satisfaction. Service advisers are friendly.
only cons is - it is lagging with the bottle holders in all 4 door pocket..
Suggestion :- Instead of discontinuing this dark horse ,One major update is required specially on back view, safety features should be from the base variant and projector lamp should be in all variant.
