Extremely disappointing car

I bought the car (City ZX , GXI)based on general reviews and perception

I am totally disappointed with the mileage in city which is never more than 7 km / litre of petrol

Repeated visits to Arya Honda Service ,from whom I bought the car, has yielded no change in fuel average.

The other very poor design element is bright reflection from the dashboard when driving in bright sunlight.

Prior to this, I drove an Indica and this vehicle , for all it's lack of sophistication, was a much better value for money.

I hope people wise-up to the fact that this is a vastly overrated vehicle and I would NEVER recommend it to anybody else.

I would very much appreciate  advice from you all as to how I should get better value from my lemon of a car.

Good looks and style. That is all.VERY poor mileage , I am getting max 7 km / lt in city and 11 on Highway
