Spark or alto which is better in hyderabad?

For a small family or for single-drive usage, if you are talking in terms of maintenance, Spark would work out to be cheaper in the initial years as Chevrolet offers 3-year free maintenance deal along with the car. In terms of negotiating everyday traffic also, Spark would be a better choice as it is smaller to maneuver and offers a higher seating position for better visibility. But in terms overall long-term cost of maintenance, better service and lower repair costs, Alto would be the car I would go with. But I think you should test drive both of them and see what suits you best. That way you will be more satisfied with your purchase. In both the cases also consider CNG/LPG versions as these will lower your fuel bills further.
