Congrats Ajay... Zest is definitely a VFM
car with practical features. And yes, a new car will give you peace of mind rather than buying a used sedan. City is a good deal. But city is known for weak steering rack which will start to show wear in 50K kms if driven rough. Also the spares in honda are costly when compared to hyundai and maruthi. Finding a well used car in today's used car market(even in company owned outlets) seems a difficult job.. So you have made a right choice.
Did you chose petrol variant or diesel variant?
